ROM codes problem with PCE, TG16

[VisitntX]

Pugsy can you lend my a hand with this one?

I tried the workaround and it works perfect, tested the codes with Magicengine, and they work fine. Now after I finished my tests wanted to start testing MESS to start to check the cheat file. The problem is that I can't make ROM codes to work for PCE and TG16. I tested NES and Genesis and they work perfect. For TG16 I even tried all MPRs. Probably is something stupid I'm missing.

BTW, posted this here cuz didn't know where to start this thread.

Have a look at some of your ROM cheats in the TG16 cheat file that I converted, eg the Invincibility cheat for R-TYPE (J):-

Code: Select all

; [ PCE/TG16 : R-TYPE (J) {CEC3D28A} ]
:tg16:CEC3D28A:60000000:000000:00000000:00000000:-= R-TYPE (J) =-
:tg16:CEC3D28A:00000000:1F0142:00000003:FFFFFFFF:Infinite Lives
:tg16:CEC3D28A:A0800000:002347:0000008D:FFFFFFFF:Invincibility::Code by VisitntX
:tg16:CEC3D28A:A0810000:00234A:000000D0:FFFFFFFF:Invincibility (2/2)

Basically you need to make sure Location = Program Space, rather than Normal or Region. So for a simple byte ROM cheat the type field should be A0800000. I've already converted pretty much all of your RAM/ROM cheats though.

Thanks Pugsy, I will take a look right now.

Yes, you converted all my codes that were made for Mednafen, but when I was converting the codes for ME found some games that needed a more proper Invincibility and I made some more codes then. It's not a huge collection of new codes, but some are pretty nice to add.

Again thanks.

Ok, now I remember how I found my codes for Mednafen. I used ultraedit to find the location in the ROM.

But thanks god I finaly found the doc that explain how memory is mapped.
