Emulator Cheats

I need some help to convert these newer cheats added to MAME but haven't been converted for use with FinalBurn Alpha and other FinalBurn Emulators.

Here's the details: (this was the format used before the cheats in MAME changed to using XML)

All other cheats I'm pretty sure are already available and working. I'll post the current cheat details used in the FinalBurn Alpha emulators for comparison so maybe anyone can help me figure it out.

The avsp cheats you posted are either relative address or bit cheats. Unless the FB cheat format has changed considerably I'm afraid you can forget about easily converting them as FB has no relative address cheat mechanism (which in fairness few emulators have) or any simple bit masking facility.

Sorry.

Here's a quick comparison:

MAME 0.126 Cheat.dat (I got this from here : http://cheat.retrogames.com/downloads.htm

Cheat File for MAME 0.126 (Release Date: 31th March 2009), I used wordpad to copy and paste this.

Select Region:

:avsp:62000000:000000:00000000:00000000
:avsp:00010000:FF81C9:00000000:FFFFFFFF:Japan
:avsp:00010000:FF81C9:00000002:FFFFFFFF:USA
:avsp:00010000:FF81C9:00000004:FFFFFFFF:Hispanic
:avsp:00010000:FF81C9:00000006:FFFFFFFF:Asia
:avsp:00010000:FF81C9:00000008:FFFFFFFF:Euro

Now the cheats used in the older FinalBurn cheat file avsp.ini:

cheat "Region"
default 0
0 "Disabled"
1 "Japan", 0, 0xFF81C9, 0x00
2 "USA", 0, 0xFF81C9, 0x02
3 "Hispanic", 0, 0xFF81C9, 0x04
4 "Asia", 0, 0xFF81C9, 0x06
5 "Euro", 0, 0xFF81C9, 0x08

So could the 'Infinite Weapon on Pickup PL1' cheat be:
0, 0xFF83DA, 0xFF ?? converted from 81000000:FF83DA:000000FF:00FF0061

Why don't you believe me?

What that cheat does it get the 16bits held at FF83DA and adds it to FF0061 to create a new address which it then pokes with FF

So for eg.
If the address FF83DA contains 0x1001 it adds this to 0xFF0061 to get FF1062
It then pokes FF1062 with 0xFF
The problem is that the contents of FF83DA are dynamic (it changes a LOT) so the address that needs to pokes varies from level to level and from game to game - that's what's called a Relative Address cheat and FB does NOT support them.

There are many versions of FBA that support the raw MAME cheat.dat file with NO conversion at all (just copy the cheat.dat to the support\cheats folder) but these relative address cheats are simply hardwired to Disabled or just ignored BECAUSE FB/FBA DOES NOT SUPPORT THEM.

OK, you're probably right. I just tested the MAME 0.126 cheat.dat in FB Alpha 0.2.97.06 and the cheats for weapon select, endless ammo from picking up weapons etc. were Disabled, and the selections cannot be made and not compatible.
