[TUTORIAL] porting romsets from hbmame #7

barbudreadmon · 2019-02-01T19:39:59Z

So i wanted to sync kof98pfe with the hbmame version (having a hack of a hack just to get it working is no good, i won't keep it in the core if it's not fixed), and i thought it would be a good idea to open an issue that might become a reference for @SumavisionQ5 or whoever who want to add support for more hacks in the future.

First, here is the original romset from hbmame :

ROM_END

I think there are 2 difficulties in this romset, which weren't handled correctly in the present implementation from @SumavisionQ5 (hence the modified 242pfe.p2 and 242pfe.p3 files).
The first one is that the 2 files aren't contiguous in memory (hence the 2M padding), iirc the correct way to do this would be more like this (updated with latest version + some comments) :

static struct BurnRomInfo kof98pfeRomDesc[] = {
	{ "242pfe.p1",  0x100000, 0x23876d95, 1 | BRF_ESS | BRF_PRG }, //  1 68K code

@dinkc64 correct me if i'm wrong, but the callback + burnloadrom thing allows to load a rom at a specific offset ? (that's what i used for the kof2k2omg hacks)

The second issue would be the ROM_FILL thing from hbmame, i think it's something like replacing data at a specific offset ? How should i deal with this in fba ?

The text was updated successfully, but these errors were encountered:

dinkc64 · 2019-02-02T00:12:52Z

Barbudreadmon, yes, of course. This topic is a great idea! Let's go:

On patching the rom, let's take for example these:
ROM_FILL(0x701af4,1,0x4e)
ROM_FILL(0x701af5,1,0x71)
ROM_FILL(0x701b18,1,0x60)
ROM_FILL(0x701ca2,1,0x60)
ROM_FILL(a,b,c) is basically memset(rom+a,c,b);

But, let's do it in a bit differently - to learn some other methods:

UINT16* ROM = (UINT16*)Neo68KROMActive;
ROM[0x701af4 / 2] = 0x4e71; // word-write nop
Neo68KROMActive[0x701b18] = 0x60; // byte-write 0x60
Neo68KROMActive[0x701ca2] = 0x60; // byte-write 0x60

Let's explain a few things:
0: Neo68KROMActive is a byte-array, but can be word(UINT16)-accessed using a simple cast.
1: notice the first 2 ROM_FILL's are contiguous? 0x701af4, 0x701af5, that's why we are able to write both bytes at once using a UINT16 cast for ROM[]. 0x4e71 is commonly known as NOP on 68k cpu's
2: notice the /2 when writing a word using ROM[]? When indexing using UINT16 (word), each word address is 2 bytes, that's why the address is divided by 2.
For example:
WORD0
BYTE0,BYTE1
WORD1
BYTE2,BYTE3
WORD2
BYTE4,BYTE5
.. and so on :) Take for example BYTE4, divide that by 2 and you get WORD2.

Maybe you just want to do it exactly the same way as HBMAME?
Neo68KROMActive[0x701af4] = 0x4e;
Neo68KROMActive[0x701af5] = 0x71;
Neo68KROMActive[0x701b18] = 0x60; // byte-write 0x60
Neo68KROMActive[0x701ca2] = 0x60; // byte-write 0x60

or even with memset():

memset(Neo68KROMActive + 0x701af4, 0x4e, 1);
memset(Neo68KROMActive + 0x701af5, 0x71, 1);
memset(Neo68KROMActive + 0x701b18, 0x60, 1);
memset(Neo68KROMActive + 0x701ca2, 0x60, 1);
... and so on...

hope this clears some things up :)

best regards,

dink

Updated the first post with latest version of the code.
It's currently crashing with the following trace :

Seems like it's failing on BurnLoadRom(Neo68KROMActive + 0x700000, 2, 1);, any idea ?

dinkc64 · 2019-02-02T14:05:57Z

Looks like we'll need a kludge in neo_run for this set to have it allocate the required memory for the main roms. try this:
edit neo_run.cpp, search for burnmalloc(ncodesize
add this line above it:
if (!strcmp("kof98pfe", BurnDrvGetTextA(DRV_NAME))) nCodeSize[nNeoActiveSlot] = 0x720000;

in the driver d_neogeo, remove the extrarom stuff & change a things a bit:
if (nRet == 0) {
rom = (UINT16*)Neo68KROMActive;

	for (INT32 i = 0; i < 0x100000/2; i++) {
		if (rom[i] == 0x4e7d) rom[i] = 0x4e71;
		if (rom[i] == 0x4e7c) rom[i] = 0x4e75;
	}

	for (INT32 i = 0x700000/2; i < 0x720000/2; i++) {
		if (rom[i] == 0x4e7d) rom[i] = 0x4e71;
		if (rom[i] == 0x4e7c) rom[i] = 0x4e75;
	}
}

.. and should be good :)

@dinkc64 got the game working with "official" kof98pfe from hbmame (see commit above), some details :

if (!strcmp("kof98pfe", BurnDrvGetTextA(DRV_NAME))) nCodeSize[nNeoActiveSlot] = 0x720000;

I think i understand this part, we need an allocation of 0x700000+0x020000 which is last 68k code rom offset+size, and it was previously failing because fba compute it only from file size by default (which makes me realize that maybe we are over-allocating 68k code memory for the kof2k2omg romset, it's computed 0x3bd4c1+0x400000 while we only need 0x100000+0x400000, but maybe that's not an issue ?).

I got a similar issue with the sound data roms and fixed it like this : https://github.com/libretro/fbalpha/blob/f9f067906613181615aca662baafd281d169300e/src/burn/drv/neogeo/neo_run.cpp#L675
There are 4 roms of 0x400000 each for sound data, which is 0x1000000. However i don't understand why there was no crash with previous version of the implementation (size is the same)

I didn't understand the changes in kof98pfeInit, and actually the game will stop working (black screen after the neogeo logo) if i apply those changes (edit : actually i understand what you are trying to do now, however it's still not working for some reason). Here is the code i tried :

Nice job figuring it out :)
So basically, the rom search & replace code is not needed then, right?

barbudreadmon · 2019-02-03T08:29:56Z

@dinkc64 it's needed, but i'm just not too sure why

static INT32 kof98pfeInit()
{
	NeoCallbackActive->pInitialise = kof98pfeCallback; // Use this callback when loading the romset

	INT32 nRet = NeoInit();

	if (nRet == 0) {
		kof98pfeExtraROM = (UINT8*)BurnMalloc(0x20000);

		if (BurnLoadRom(kof98pfeExtraROM, 2, 1)) return 1;

		UINT16 *rom = (UINT16*)kof98pfeExtraROM;
		for (INT32 i = 0; i < 0x20000/2; i++) {
			if (rom[i] == 0x4e7d) rom[i] = 0x4e71;
			if (rom[i] == 0x4e7c) rom[i] = 0x4e75;
		}

		rom = (UINT16*)Neo68KROMActive;

		for (INT32 i = 0; i < 0x100000/2; i++) {
			if (rom[i] == 0x4e7d) rom[i] = 0x4e71;
			if (rom[i] == 0x4e7c) rom[i] = 0x4e75;
		}
		
		SekOpen(0);
		SekMapMemory(kof98pfeExtraROM, 0x900000, 0x91ffff, MAP_ROM);
		SekClose();
	}

	return nRet;
}

works and

static INT32 kof98pfeInit()
{
	NeoCallbackActive->pInitialise = kof98pfeCallback;

	INT32 nRet = NeoInit();

	if (nRet == 0) {

		UINT16 *rom = (UINT16*)Neo68KROMActive;

		for (INT32 i = 0; i < 0x100000/2; i++) {
			if (rom[i] == 0x4e7d) rom[i] = 0x4e71;
			if (rom[i] == 0x4e7c) rom[i] = 0x4e75;
		}

		for (INT32 i = 0x700000/2; i < 0x720000/2; i++) {
			if (rom[i] == 0x4e7d) rom[i] = 0x4e71;
			if (rom[i] == 0x4e7c) rom[i] = 0x4e75;
		}
	}

	return nRet;
}

don't.
With the third c68k code rom already loaded, patching directly on Neo68KROMActive makes more sense to me.
if (BurnLoadRom(kof98pfeExtraROM, 2, 1)) return 1; is definitely needed (black screen without it), while it's returning false (because BurnLoadRom(Neo68KROMActive + 0x700000, 2, 1); was called in the callback i guess), so i'm not too sure what is happening behind the scene. If you have any explanation i would be curious.

Oh, ok, I must have looked at the wrong code in hbmame then when I came up with that alternate init. oops :)
BurnLoadRom shouldn't return bad if you load a rom a second (or third) time - that's odd :/ Try ignoring the load status?

BurnLoadRom shouldn't return bad if you load a rom a second (or third) time

My bad, it seems the good return value for BurnLoadRom is actually 0, so having the return value equivalent to false is actually a good thing.

I think the code you looked at in hbmame is the right one.
You can see the same kind of differences for lastbladsp between hbmame and fba : https://github.com/Robbbert/hbmame/blob/fce87309c706c6e9626bdc735ed82eddef342811/src/hbmame/drivers/nglastblade.cpp#L8-L28 and https://github.com/libretro/fbalpha/blob/89aaee4338869b3f8f10df97023353805846c4bf/src/burn/drv/neogeo/d_neogeo.cpp#L15733-L15770

I don't understand why, in both cases, direct access to Neo68KROMActive doesn't work for this 3rd rom, but you can backport the kof98pfe romset to standalone anyway.
