I remember that Mezmorize starting doing his codes a little different, but don't remember the details. If you start reading his posts on that thread from the beginning, you'll probably find an explanation by him on how to apply his codes.

Have had a look and can't figure it out :-/

Can someone clarify how to do the Soul Star one (as the IPS is for a different CRC than my ISO). What bytes are we searching for, and what are we changing them to?

Thanks

Seems you can't alter anything in the ISO or it won't get past the Psycnosis logo...

ok try but workin in the 1 stage no idea!

[Tony H]

Don't use the ips, just use a hex editor.

[yolomate]

no workin! I try again and now put again that ips for infinite lives and not work too! no idea

[Tony H]

I put that ips patch and no got infinite lives why??

Try doing it manually with a hex editor. And make sure you do it to all 10 matches.

[yolomate]

Good to hear it worked for you.
I didn't really think about it before, but I guess the patches would also work for non iso/mp3 rips as long as the audio is stored at the end of the disc.

Here's some text:

PUSH START BUTTON
MAP #0000ÿ
TOWN #0000ÿ
REAL #0000ÿ
STATUS #0000ÿ
KING #0000ÿ
DEBUG #0000ÿ
FLAG #0000ÿ
MODE #0006

I put that ips patch and no got infinite lives why??

But work only on first stage

If you know how to use a hex editor, you can easily fix this. Just open up your iso file with a hex editor and search for and change every occurrence of the string mentioned in the post.

Does anyone know if Sega CD can use a checksum check on startup? I made a change to the Lunar 1 ISO and now the game won't run (only gets to the title screen). Never had this problem with any other SCD ISO. Any info would be appreciated. Haven't done any SCD stuff in a long time, so I'm a little rusty.

Anyways andwan0, here is a RAW code for infinite money. I tested it with Gens r57 and it worked fine. Should work on any Gens emulator that supports cheat codes and SCD.
