Author Topic: MAME to FBA conversion code (Read 8724 times)

The main idea of this thread is to give a reference library to anyone who wants to port MAME code to FBA.

MAME <--> FBA conversion code

memory_region(REGION_CPU1) -> Neo68KROM
memory_region(REGION_CPU2) -> NeoZ80ROM
memory_region(REGION_GFX1) -> NeoTextROM + 0x20000
memory_region(REGION_GFX3) -> NeoSpriteROM

Here's a site that shows the different data types between C and C++

Here's a site that can help explain some common and useful functions:

Did you finally break down and decide to import some of MAME's functions into FBA?

Anyone can tell me how to change this MAME code MRA16_RAM & MWA16_RAM to FBA,thx.

In that means, how to define MRA16_RAM & MWA16_RAM in FBA？

I hope some can tell me how to covert this code to FBA,thx.

Code: [Select]



static UINT16 mv0_bank_ram[ 0x10/2 ];

static READ16_HANDLER( kof2003b_prot_r )
{
	return mv0_bank_ram[ 1 ];
}

	memory_install_read16_handler(0, ADDRESS_SPACE_PROGRAM, 0x??????, 0x??????, 0, 0, MRA16_RAM);
	memory_install_write16_handler(0, ADDRESS_SPACE_PROGRAM, 0x??????, 0x??????, 0, 0, MWA16_RAM);

	memory_install_read16_handler(0, ADDRESS_SPACE_PROGRAM, 0x??????, 0x??????, 0, 0, kof2003b_prot_r);

then kof10th can work on FBA,^_^.

Jeje bms, why don't you try you own bankswitch code? (the one you use for svcchaos, kof2003, mslug5 and other games, they include the extra ram needes by that games and even kof10th...
The protection check fro 2fe000, 2fffff mem dirs are in fact the bankswitch needed, this game seems to need only the mvo prot (or bank) bankswitch + 2 extra RAM modules (maybe we have emulated that already in fba)
See ya!!!!!!

FerchogtX was a really clever guy.

It does not need the kof2003 bankswitch

XD check the other posts James... but anyway isn't exactly kof2003 bankswitch
See ya!!!!

No need as I have the needed bankswitch code

And its not MVO or kof2003 bankswitch.
