Second patch works flawlessly! Great work GDX!!! Smile
I don't mean to sound too demanding, but I hope at some point you can take a look at these which also don't work on real MSX with rom loaders:

1) DONKEY KONG (OCEAN SOFTWARE) 48 kb version CRC: 5640E6E2 - Doesn't work at all.
2) DOUBLE DRAGON (ZEMINA) 32 kb CRC: C70E3A34 - Enemies don't move.
3) GUN.SMOKE (PROSOFT) 32 kb CRC: 1318DBA7 - Shoots in right direction only.
4) KNUCKLE JOE (PROSOFT) 32 kb CRC: 33BE6192 - Hangs on title screen (this game seems to be a hack of Jackie Chan The Protector but better than the original in my opinion).

Thanks!

This Donkey Kong has a size of 48kB but it use SCC mapper. EXECROM or ODO can't launch it. Try with Sofarom.

Gun Smoke has a anti-piracy protection by software. Replace the byte C9 by DD at 00094Ch then 12 by C9 at 000E14h, that should remove it.

Double Dragon:
Try to replace the bytes 36 C3 by 00 00 at 00094Ch then 12 by C9 at 0010CBh

Knuckle Joe:
00 00 3E 04 32 B5 41 -> C3 B2 41 00 00 3E CD at 00019Eh
80 BF -> 74 41 at 000619h
Then, for a better support with Rom loaders fill from 00005h to 00001Fh with 00h. (to clear the header and the remaining waste)

OMG they work!!! Eek!
Thank you GDX... those will keep me busy for a long time!
Already played Double Dragon and reached stage 2. No issues. However I had to patch bytes 36 C3 by 00 00 at 10CBh (you got it mixed with the other offset) and I wasn't sure about 12 by C9 because it doesn't match at 94Ch. So I patched the nearest 12 I could find which was at 934h. Is this correct?
Knuckle Joe was exactly as you said and seems to work perfectly fine.

It is a mistake to Copy/Paste for Double Dragon. Replace only the bytes 36 C3 by 00 00 at 0010CBh. That should be enough.

Looking more closely, I realized that Donkey Dong (Ocean) is compatible with Konami's mappers with or without SCC, and also Zemina 8k. I made a patch to add the ASCII 8k mapper support. Now the game can work on many devices (ESE-RAM ASC8/SCC, KOB, MAB, Megaflash ASC8/SCC, MegaRam, etc but not in RAM.)

It's indeed the Konami Generic mapper in blueMSX.
