    • IGS PGM English Patch Index

      This thread will serve as an index for any links to IGS PGM game patches that allow for English text on original game cartridges.

      No ROM files will be provided, only xdelta patches that can be applied to your own game ROM using tools like 'xdelta UI'.

      DoDonPachi II - Bee Storm
      Knights of Valour: Super Heroes
      Knights of Valour: Super Heroes Plus
      Knights of Valour 2: Nine Dragons
      Martial Masters (Also unlocks all characters)

      KOV and KOV Plus patches work in MAME but not on real hardware, so they are not linked.

      The 'Type 3' games (Demon Front, The Gladiator, Killing Blade Plus, Spectral vs Generation, etc) unfortunately will likely never see English patches, as they run almost entirely from the ARM chip and the 68k processor is mostly used for I/O.

      Other games like Oriental Legend only change the title screen and no other in game text, so there is little usefulness patching those titles.
    • I did a Marshal Masters patch today. After inspecting the patch... I thought these were stock roms and some one has edited the roms to convert to english. BUT it would seam there just the Stock ENGLISH PROG ROMs from stock english / USA region carts.... (Correct me if these are done by hand) i translated a couple of SNES games from scratch....

      IF this is correct, I should be easily able to go through all the English carts i have and dump the PROGRAM ROM from each cart. Since i almost have a complete collection... This SHOULD bring out a lot of roms! I can host them on my site as well....

      In theory you COULD go through all the MAME roms... BUT it won't always give you the langue and version number of the rom..... (Which you need)

      There is ONLY a few possible issues (And maybe this is how some patches do NOT work on a real cart.)

      1. Your not meant to be able to change the region. Its meant to be locked in ARM protection chip. BUT i have swaped around PROGAM ROMs BEFORE.. and have changed the region. Maybe the region is in the ARM ROM and ARM CPU.. and as long as these match.. the program rom is decrypted and runs ??

      2. Also i think the ARM ROM and PROG ROMs are meat to be in matching "pairs" / Versions. So depending on which Program rom you have... may need a specfic ROM/Patch for your cart.

      I am pretty sure that they are just stock English ROMs from US region carts. They were discussed previously here.

      @skate323k137 graciously burned me one for my MM.

      The ARM chip decides the region, the program ROMs will be the same for a given revision.

      What these patches do is disregard the region the ARM spits out and instead use the English / Export region in the 68k code.

      The ARM ROM version does not need to match M68K ROM version, at least from what I've seen and gathered from those that have given this a try.
    • Doing non translation stuff i have found issues when changing program roms and leaving the ARM/ASIC code the same.... it was only a few games though....
      I'm going to build a database of all the English Program roms to help others mod there carts... Or i can sell modded games, or just Programed Eproms for people to replace....
      I almost have a complete PGM collection... so i''ll dump the english roms i have here... then look and see what mame roms have aswell.

      NOT all games are in MAME anyway.. I have added a handfull of them.. and another few handfulls of rom revison versions.

      I need to make a easyer to read PGM Game list toooo...
