First post, by Srecko
I implemented most "intelligent" playback functions of original Roland's MPU-401 for use with Dosbox and Roland MT-32 emulator, based on documentation someone posted (linked) on this forum.
The patch is available here.😀
Required modifications to dosbox's config files and PIC code are also included.
I was able to find only 4 games/demos to test it and they now work with emulation (using latest MT-32 sources in dosbox):
Innocent until Caught (Core Design,'93)
Curse of Enchantia (Psygnosis,'92)
David Wolf (Dynamix,'90)
Ecargxus (demo by TPC,'92)
Games are available at The Underdogs, demo at pouet.net .
Please let me know if there are any games/demos/programs that use "intelligent" mode, working or not.
Candidates: Those using strange MPU commands (other than 3F and FF), or resetting MPU 401
with FF and giving-up after that (I found out that original MPU-401 runs IRQ after reset 😕 ).
edit - now the link should work (but if it doesn't, look at "patches" section on sf.net)
