Almost works
Response from developer
Sorry about that — a disk that is read and then handed back is almost always one of two things, and both take two taps. First: importing the ROM does not select it. Open the gear menu › Kickstart ROM… and tap your 3.1 ROM; the filled check mark shows what is active. Until then Amigo is still booting its built-in AROS ROM, which most floppy games refuse. Second: the default machine is an A1200 with a 68020 and fast RAM, and games from the A500/A2000 era often reject that. Tap gear › Machine… › the A500 preset, then insert the ADF again. Version 0.7.7, in review now, adds "Why won't it boot?" under Controls & Help. It reads your ROM, machine and disk and names the mismatch. There is also a Quick Start at github.com/thomas-luebker/Amigo. If neither helps, please open an issue there with the game name and I will look — your ROM recognised and imported is the hard part done.
So close!
Response from developer
Thank you — and you were right on every point. Version 0.7.6, live since 27 August, fixes all of it. The stuck left-click and the unwanted drags had one cause: the Pencil's own tip could be mistaken for a resting palm and ignored, so a stroke's end was lost and the button stayed down. That is gone. Pressure now reaches the Amiga two ways, both under Input & Overlays: "Pencil Pressure" for programs that read the system tablet, such as Deluxe Paint, and "Serial Tablet" for TVPaint, which drives a Wacom itself. In TVPaint set the tablet Type to "Wacom A4+ Pressure" — other sizes leave the pointer stuck at the edge. Both take effect after restarting the Amiga. How much a stroke widens with pressure depends on the brush and profile you pick inside TVPaint. For selecting and dragging in Workbench with the Pencil: touch is the left button, double-tap is right-click, and hover moves the pointer without clicking on an M2 or newer iPad. If anything still misbehaves, please tell me at github.com/thomas-luebker/Amigo/issues — pressure painting on the Amiga is exactly what this should be good at.
HDDs
Response from developer
Update: this shipped in 0.7.5, live since 25 August. You can now mount several HDF images at once and they appear as separate volumes — DH0, DH1 and so on, each on its own drive — and ejecting one leaves the others running. Thanks for asking for it; your review is what put it on the list. If it doesn't behave the way you expected, tell me at github.com/thomas-luebker/Amigo/issues and I'll take a look.
