I can finally start Metal Gear 2 with the custom BIOS update now! However, there have been a few things that have stood out to me that hinder my experience. When using the function keys, even when I feel the haptic feedback from it (and the click animation plays) it doesn't register sometimes. While playing Metal Gear, it took me about 5-6 clicks to get into the utility menu to switch cards. It gets annoying fast when I'm being pursued by the enemy and I need to heal. If that could be fixed, that would be great... Another thing I noticed is that the consistency of the buttons seem a bit off... When I tap the up button, it works nearly immediately, while when I tap it again, it takes about a half-second to process it again. (Also, the haptic feedback doesn't repeat on that...) Other than those few things, this app is great! This is what pushed me to finish some games I had started. Thanks. **Developer response:** Thank you so much for your support and for taking the time to share such detailed feedback! I’m really glad to hear you’ve been enjoying the emulator and that the custom BIOS update helped you. I’ll take a close look at the issues you mentioned with the buttons and haptic feedback and will do my best to fix them for the next version. Your input really helps me keep improving the app, thanks again! ### 4/5 — DSK format support is missing *2025-10-22* It is a great emulator, but lacks the support of DSK type, I’m looking forward to see it supporting this format in the coming updates. **Developer response:** Thanks a lot for your feedback! Since version 1.7, iMSX2 supports DSK files. Just remember you’ll need to add a real BIOS to get them running correctly. ### 4/5 — Metal Gear 2: Solid Snake is broken *2025-09-06* I have played Metal Gear and Penguin Adventure and they run well with minimal problems, but I have been having a lot of trouble trying to run Metal Gear 2: Solid Snake. Is there a reason it doesn’t start? **Developer response:** Thank you for your feedback! I’m currently working on this issue. It seems that Metal Gear 2: Solid Snake uses save data, and the emulator is having trouble reading that part of the memory, which is why it’s not starting properly. In addition to fixing this, I also plan to add support for external BIOS files besides the current C-BIOS. Hopefully this will improve compatibility overall. Thanks again for your support and patience! ### 4/5 — Genial, pero… *2024-07-08, version 1.4* Es genial poder volver a jugar aquellos fantásticos videojuegos de los msx en el móvil. La app está muy bien y es muy intuitiva pero: 1) Hay roms que no hay forma de que funcionen y que, sin embargo, en el Mac sí que funcionan con otro emulador (por ej, el juego Beamrider) 2) Tengo hemiparesia debido a un ictus que tuve ha años y que me impide usar la mano derecha. Sería de muchísimo agradecer que el emulador tuviese un modo “auto-fire” o que los “disparos” estuviesen integrados en los cursores. Somos mucha gente en condiciones similares los que nos encontramos con la barrera de que si no tienes las dos manos para jugar… lo tienes muy difícil. Gracias de antemano ### 4/5 — It is not 2+ *2024-06-13* It's a good start, but the machine type can't be selected, no FM sound in any ROMs I tested (only PSG), no support to .dsk files, no support for mass storage, no extensions, no support for simultaneous ROMs in different slots. I believe this emulator will evolve with time, it has a good UI and is promising. **Developer response:** Thank you for your feedback! I understand there is still much to implement, and I've focused on starting with the basics. The plan is to gradually add as many features as possible. I appreciate your comments and support. ### 3/5 — En desarrollo *2024-06-03, version 1.3.1* Queda mucho por hacer y pulir. Al principio es frustrante porque apenas consigues hacer funcionar homebrew. Mejor empezar por los Konami de toda la vida. Importantísimo mejorar la autodetección del tipo de cartucho y poder elegir el MSX emulado. Otra cosa pendiente es poder usar el ipad en horizontal y a pantalla completa. Habrá que tener paciencia. ### 4/5 — Looks good but… *2024-05-30* Music/sound does not works. **Developer response:** Thank you for your feedback and comments. We're actively working to resolve the audio issue, and it seems that when background audio is playing or if the silent mode is enabled on iOS, sound does not play even if background audio is turned off. Sometimes, toggling the silent mode on and off helps. ## Most critical reviews (10 lowest-rated) ### 1/5 — 何も動かない *2026-08-08* 買ってはいけません。 **Developer response:** ご購入いただきありがとうございます。 何も動作しないとのことですが、具体的にどのような問題が発生していますか？また、どのゲームで問題が発生しているか教えていただけますでしょうか？ もし問題が解決しない場合は、詳しい状況を e7company@gmail.com までメールでお送りください。できる限り対応いたします。 なお、iMSX2 は .rom、.mx1、.mx2、.dsk 形式のゲームに対応しています。 また、画面上部のリストから MSXのモードを変更して試してみることもできます。それでも動作しない場合は、実機のBIOSを追加して試してみてください。 ご不便をおかけして申し訳ありません。問題の詳細を教えていただければ、原因を確認したいと思います。 ### 1/5 — Can’t open ROM files *2025-04-25, version 1.6* Keeps getting an error about “Init ROM in slot” and can’t play my games. I hope for some support. ### 1/5 — Timo *2024-08-22, version 1.5* No carga ni una rom ni nada, quiero mi dinero por favor. ### 2/5 — Metal gear 2 solid snake *2025-08-14* Due to the nature of this app, I am unable to load this game because this is a stripped down version of the emulator that defaults cbios, which are incompatible with mg2ss, very unfortunate because that’s the only reason I bought this app. If There’s a way to fix this I’d be open to it but Ive wasted my money otherwise 😖 **Developer response:** Thank you so much for your comment and feedback. I’m working hard on getting this game to run properly. It looks like it uses save data or some part of memory I haven’t fully accounted for yet, which prevents it from initializing correctly. I really appreciate your support and I’m committed to improving the app, I hope to release a new version soon that fixes this issue. My goal is also to add the option to use your own BIOS in the future, so compatibility can be greatly improved. ### 2/5 — need more works on this app. *2024-08-26* 1. I hope you can make good UI functions if you just use msx core. 2. After setting the game cartridge and playing, I don't know how to return to basic basic mode, and I don't know why it has to be so cumbersome. 3. There is no way to turn off the overlay touch UI. If you let the game controller use it, of course, you should provide the function to erase the overlay UI. 4. There is no function to adjust the screen aspect. I hope you continue to improve and pay for the app price. **Developer response:** Thank you for the feedback! I appreciate your detailed input, and I’ll work on addressing all the points you’ve mentioned. I’ll keep improving the UI functions and make the experience smoother and more intuitive. Thanks again for your support! ### 3/5 — Metal Gear 2 solid snake not working *2026-07-28* Hello, I paid for this app exclusively to try and use metal gear two solid snake, it is not working, the first metal gear does, 2 does not **Developer response:** Hi! Thanks for your support and for letting me know. I'm happy to say that starting with iMSX2 version 2.0, Metal Gear 2: Solid Snake is now fully playable. This was one of the main improvements in the latest update. Please update iMSX2 to version 2.0 from the App Store and give it another try. I hope you enjoy the game, and thanks again for your support! ### 3/5 — Con mucho campo para mejorar *2025-08-18, version 1.6.5* El funcionamiento con teclados bluethoot es bastante deficiente (por no decir que no se pueden usar). Seria ideal poder ocultar los controles de juego en la interfaz, ya que si usas un teclado externo pueden no ser necesarios y molestan en la pantalla. También sería genial poder entrar en el modo BASIC para poder hacer algún que otro programita simple y poder guardar/recuperar, sobre todo si quieres hacer algo más didáctico con los nanos. Creo que lo que hacen emuladores como CPCESP o Spectaculator es el camino a seguir. ### 3/5 — Can not play Metal Gear 2: Solid Snake *2024-12-30* Can not play Metal Gear 2: Solid Snake **Developer response:** Thank you for your message. I’m currently working on resolving this issue. It seems to be related to the game using save files, and there’s an error when reading the memory for those saves. As mentioned, I’m actively working on it, and the next version should have this problem fixed. Thank you for your support, and best regards. ### 3/5 — Non male ma… *2024-12-08, version 1.5.5* Niente male però manca la tastiera MSX. Alcuni giochi ne hanno bisogno e, senza, non possono essere usati ### 3/5 — Needs plugged-in controller support *2024-06-11* I have a gamesir controller for my iPhone, similar to the backbone controller. It’s not Bluetooth, it plugs in via lightning port. If this app had horizontal full screen support and the ability to control the app with my plugged-in controller, it would be perfect. **Developer response:** Thank you for your feedback! I'm happy to share that our next update will include support for the new horizontal design. Regarding the Gamesir controller, I will investigate how to integrate support for it in the app. Stay tuned for more updates! ## Most praised reviews (10 highest-rated) ### 5/5 — 아이폰 유일의 msx앱이고(레트로아크로 실행은 가능하지만 불안정하고 무료앱이라 업데이트가 안됨) *2026-08-25* 아직 완벽하지는 않지만 초기의 문제점 및 보완 사항을 피드백 했을때 제작자님이 바로 수정 보완 업데이트 해줘서 믿음이 가며 앞으로도 꾸준히 발전할 앱이라 믿어 의심치 않습니다. msx 의 추억이 있고 그 추억을 다시 경험하고 싶은분이라면 필구앱이라 생각합니다. ### 5/5 — Está muy bien *2026-02-06, version 1.8* Se puede mejorar pero me gusta mucho, el esfuerzo merece 5* ### 5/5 — It's Working *2025-12-06* With machine selection I could use it for the first time! **Developer response:** I’m really glad to hear that! I’m constantly adding new features whenever I can, often based directly on user requests. If you think of anything that could improve the experience, feel free to let me know. Thanks a lot for the feedback and support! ### 5/5 — Audio bugs have been fixed, now definitely my favorite Mac emulator *2024-06-09* I’ve reveiwd a few times here before. I’m happy too say that the audio issues I’ve been expieriencing have since been fixed with the last update. Can’t wait too see what comes next. **Developer response:** Thank you for your feedback and comments! I'm sorry to hear about the sound issue you're experiencing. I'm actively working to resolve the audio issue, and it seems to be related to what you've mentioned. Regarding writing in BASIC, for an upcoming version, I plan to add compatibility with Bluetooth keyboards. However, it's important to note that MSX-BASIC is not currently available for legal reasons. To address this, users will have the option to add a real BIOS in a future update if they have the necessary permissions. Thanks again for your valuable feedback. ### 5/5 — Exciting times for the App Store *2024-05-26* This app shows so much promise. It’s so exciting to have options like these in the App Store :) **Developer response:** Thank you so much for your kind words! I'm thrilled to hear that you're enjoying the app and find it promising. I'm committed to continually improving and adding new features to make your experience even better. If you have any suggestions or feedback, please feel free to share them with me. Your support means a lot! :) ### 5/5 — Great emulator for a semi obscure system, though with one issue *2024-05-23* This is a continuation of my last review. Emulator still works great however I now have sound working. At times anyway. It seems when background audio is being played or if iOS has silent mode on it won’t play sound, even if you turn off background audio. Turning on and off silent mode sometimes helps and sometimes not so I’m sure it has something too do with that. Other then that it’s been great for playing old Mac games and testing out old basic programs. Though it would be cool too have a way too write basic in the app like old systems of the day. Keep up the good work dev. Hope too see this evolve and maybe even more emulators someday **Developer response:** Thank you for your feedback! I'm sorry to hear about the sound issue you're experiencing. I'm currently investigating this problem and working on a fix. In the meantime, please change and try a different configuration for that ROM. We appreciate your patience and will keep you updated on our progress. ### 5/5 — Buen emulador *2024-05-20, version 1.1* Buen emulador y sobre todo lo que es de muy agradecer, sin publicidad. Se agradecería muchísimo soporte para iPad y también para mandos y teclado externo (con eso tendríamos un msx portátil con teclado y todo). ### 5/5 — It’s a great msx series emulator, however *2024-05-20* I can’t seem too get the sound to work so far. It runs fine but stays silent. Other then that it performs smoothly **Developer response:** Thank you for your feedback! I'm sorry to hear about the sound issue you're experiencing. I'm currently investigating this problem and working on a fix. In the meantime, please change and try a different configuration for that ROM. We appreciate your patience and will keep you updated on our progress. ### 5/5 — Awesome app but one suggestion *2024-05-20* Is it possible to implement an on screen keyboard that could be used at the bottom of the screen when needed? It would be incredible to see this added in a future update 💕 Arigato **Developer response:** Thank you for your suggestion! An on-screen keyboard is one of the features I plan to add in future updates. I'm also working on adding horizontal layouts and optimizing the app for iPad. Including an on-screen keyboard would indeed be a great addition, and I’ll definitely consider it as I develop these updates. Arigato for your support! 💕 ### 4/5 — Great support for MSX, but.... *2026-02-03* The best support I have found for MSX. The interface is clean and user friendly. My one issue is the touchscreen d-pad. Something is off to where you cannot make multiple fast inputs. It registers one click immediately but not the next. I found it unplayable with the touchscreen but fared better with a controller. **Developer response:** Thanks a lot for your feedback, I really appreciate it. I honestly hadn’t noticed that specific behavior with the touchscreen D-pad before, so thanks for pointing it out. I’ll definitely take a closer look at it and try to fix or improve it in a future update. Comments like yours are extremely helpful and really motivate me to keep improving the emulator, so thank you again for taking the time to share your experience. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
