I tried bmhat.ttp (as I hadn't before) in VGA mode just to see if that were the issue and sadly not. Same as the other failures, it gets past the menu screen and then as proper rendering commences, the screen breaks down and ends up black.dml wrote: ↑Fri Sep 30, 2022 4:16 pm BM does attempt to split-screen for the status bar (changes video mode at line #168), which is a bit rude on VGA probably. Maybe it is something to do with that. Although it is more likely a signal issue in the Falcon (while doing that, or while hitting the DSP... or some other noise).
The only build of BM that does not do this is bmhat.ttp - the Hatari build. Simply because Hatari doesn't emulate Videl register changes mid-frame, so drawing the status bar needs workarounds.
Can hear the sound effects, so the game is running!
If it's running from ST-RAM there won't be much up-changing anyway, so perhaps that's actually what's allowing it to work?dml wrote: ↑Fri Sep 30, 2022 4:20 pmI'm kind of amazed the bm030.ttp binary works under those conditions. It doesn't bother handshaking with the DSP except when there is no other choice. But if it works it works
