I have created a trainer version of some games. I know that people liked the Strider and Ghouls'n Ghosts Trainer versions, so I decided to make 3 more versions: Final Fight, Magic Sword and Willow.

Notice that the patch of Final Fight is not perfect, but should me more than enough to "train" you in the game which I believe is the goal.

I have included only the maincpu.03 file for each game. You need to copy it into the right folder and change the file NAME adding to the end the TRAINER word if you want.

Please try it and let me know how it works for you!!!

Enjoy and let's 1CC all those games!

Looks like you liked this initiative, so I've worked on the trainer for Varth. See attached. Please let me know how it works for you.

Thanks!

If i wanted to load it up in mame, would I split / de-interleave maincpu_msword_trainer.03 into this file set?

ROM_REGION( CODE_SIZE, "maincpu", 0 ) /* 68000 code */

Yes basically that is what you need to do. I can post thos3 changes later, if you want.

Do you have info on the Ghouls Trainer? Would love to install in a CPS1 conversion so I can cheat, I mean train to get better at it. Love the game, would prefer godmode as opposed to continue x10 tries to get to level 3 :)
 
Ha, is "trainer" the new word for cheater?!?

I love it, keep 'em coming Darksoft! And yes, I rolled with a Game Genie BITD! You're our modern day Robin Williams!

Okay, so I am still a putz. I have Ghouls romset opened up (world) and I cant find which BIN is MainCPU3 per posts above so I know which to apply patch to?

Note, I am trying to make a romset to play on a conversion CPS1 boardset, not just in MAME. Not sure if that is the root of my problem.

If you look at the mame driver you will see how these games are loaded into memory:
https://github.com/mamedev/mame/blob/master/src/mame/capcom/cps1.cpp#L4542

As you can see the region maincpu loads the 4 first eproms using the function "ROM_LOAD16_BYTE" which reads one byte from the eprom and skips one, so basically dme_29.10h stores even bytes from 0 to 0x40000 and dme_30.10j odd bytes also from 0 to 0x40000

The first patch is for address 61B8A and you should check in the next 2 eproms (dme_27.9h and dme_28.9j )

but the ones for 513A, B62E, B630 and B3F4 are in the first 2 eproms that I mentioned (dme_29.10h and dme_30.10j ).
Now to change the byte at address memory 513A, you need to go to the eprom holding that byte which is dme_29.10h, but as we only have even bytes here, the offset to modify will be 513A / 2 = 289D. So edit that eprom file with an hex editor, go to offset 289D and start modifying the even bytes. That means change to:
11 00 00 11 00 00 4E
and then go to that same offset in the other eprom and change the bytes at offset 289D as well for the corresponding odd bytes.

I am either going to learn a whole ton on address / bitlevel changes or my brain will explode, will try and report back if I dont die from an aneurysm.

Will have to delete some SCUBA info from my databanks to make room for new skills.
