The attached patch fixes the PQ4CD GM driver, and it appears to cause no problem with the usual suspects (MechWarrior, It Came From The Desert, Innocent Until Caught, Curse of Enchantia, Legend games, several sequencer apps). It will need plenty of testing to make sure nothing else becomes broken. …

it worked just fine in 0.74 as far as I can tell. So, strange colors instead of the correct white on black and keyboad problems are "working fine"?

Tests have shown that the MPU-401 (external) becomes busy for 27ms after a reset command is received, and it won't process further commands during that interval, although one command can be queued pending completion of the reset. Maybe a reset command received while a reset is in progress is …

I wouldn't worry too much about how the game works with the PCjr machine type unless there is some evidence that the game should work with it. Yes, there are similarites between Tandy and PCjr, but they're not the same. It may have worked better with PCjr in 0.74 owing to the similarity, but the …

The older version (1998 date stamp) of the Pirates! booter from Retrograde Station works OK in SVN, but the newer version (2006 date stamp) crashes. The newer version was supposedly given an improved crack by Demonlord (owner of RS). Newly added crack code is placed 4 kB below the top of memory as …

It works if you go down to 1000 cycles, but that's far too low for the game. The CD version GM driver is different than the one in the floppy version, despite both being internally labelled as v1.08. The CD version driver has a problem with the reset delay that was implemented in the MPU401 device: …

Seems unlikely that the GENMIDI.DRV driver would be significantly different between floppy and CD version... Some of the MPU changes are related to timing, so try reducing cycles (fixed or limited).

The error message is misleading; the actual problem is a DPMI memory allocation error. The error happens when the game shells out to run the SMACKPLY.EXE player program, but not when you run the player at the prompt with the same parameters. The player program uses the Causeway DOS extender, but it …

Try different loadfix allocations. Even "loadfix -f" that frees a few default memory blocks seems to be enough to avoid the hang on exit.

That's mode 6? I wonder because you get 80-column text (hard to read in composite) unless you use some tweak (e.g. set mode 4 and switch to hi-res by writing to the CGA mode register, so you're in mode 4 as far as the video BIOS knows when drawing text). 'Tis indeed interesting that it's the same …

The RGB or composite choice you mention only works in the original Tapper booter. I can tell from the program name in the title bar and your screenshots that you're running a RGB DOS conversion, and what you're looking for is the composite DOS conversion (which works in 0.74 or SVN).

The crash at startup happens only sometimes on my system with cycles=auto, and appears to be caused by the game uninstalling its SB interrupt handler before the interrupt fires, meaning the interrupt is too slow or the code is too fast. I find the crash happens infrequently with "cycles=auto limit …
