Hope lr-fbneo support kof 97 practice mode(kof97pm.zip)

@ninja You could probably do it, I think, in the same way as I did with some of the Donkey Kong hacks.
@barbudreadmon Yes, that is correct. I do not have any programming skills (and, as a result, you did help me a great deal getting Donkey Kong hacks to work, which I appreciated).

ninja

@barbudreadmon OK, thanks. I'll give it a try

You mean the sdl errors ? I don't know, i don't use the sdl port, try with the libretro port instead ?

ninja

@barbudreadmon
Let me explain what I did in detail.

I downloaded Fbneo and extracted all files in the .zip file.

After adding support information to kof97pm.zip in file:

FBNeo-master/src/burn/drv/neogeo/d_neogeo.cpp

I compiled fbneo under FBNeo-master with command

 make pi

and got an executable

fbneo

I tryied to run it and encountered error above.

After checking the post Donkey Kong Spooky Remix in Retropie? and the directory structure of Retropie, I found what I need is actually

fbneo_libretro.so

Then I went to

FBNeo-master/src/burner/libretro

and recompiled with

make -j5 -f Makefile platform=rpi3 clean
make -j5 -f Makefile platform=rpi3 generate-files
make -j5 -f Makefile platform=rpi3

then I got

fbneo_libretro.so

I moved it to

/opt/retropie/libretrocores/lr-fbneo

and replaced the file of same name there.

Now what else do I need to do ?

Nothing, if you launch kof97pm with fbneo through emulationstation it should use your custom compiled core

ninja

@barbudreadmon

But I have recompiled

fbneo_libretro.so

and placed it in

/opt/retropie/libretrocores/lr-fbneo

So now I can play kof97pm from the EmulationStation interface, just like any other roms in Retropie ?

barbudreadmon

@ninja yes

ninja

@barbudreadmon OK, I'll give it a try this evening.
BTW, can I submit my changes of FBNeo to it's master branch(also to RetroPie)?

If so, future versions of FBNeo and RetroPie will support kof97pm by default, and all global users can play this game automatically in future.

Sure, you can submit it to https://github.com/finalburnneo/FBNeo

Do you know how to set BIOS for kof97pm ?
Because If I want to play kof97pm in practice mode, I have to use UniBIOS(which is in neogeo.zip).

But I don't know where and how to set a BIOS for kof97pm in RetroPie.

Use the Core Options in RetroArch's quick menu to choose between BIOS versions.

ninja

@mitu Is it possible to specify a BIOS only for kof97pm ?

mitu

@ninja Yes, Core options can be saved per-game - there's a menu entry on top of the option list that does that. Just set the options you want for the game in question (opening the RGUI while in-game), save them, then set the options back to the values you want to be the default.

ninja

@barbudreadmon Thanks for your help. Now I can run kof97pm on my RetroPie.

But there are still some small problems. For example, I cannot see clearly the words on the screen when playing kof97pm.

I guess it's because the support codes added to d_neogeo.cpp might not be complete. So I attached these codes below:

// The King of Fighters '97 Practice Mode

static struct BurnRomInfo kof97pmRomDesc[] = {
        { "232pm-p1.p1",   0x100000, 0x34ccabae, 1 | BRF_ESS | BRF_PRG }, //  0 68K code 
        { "232-p2.sp2",   0x400000, 0x158b23f6, 1 | BRF_ESS | BRF_PRG }, //   1

        { "232-s1.s1",   0x020000, 0x8514ecf5, 2 | BRF_GRA },          //  2 Text layer tiles

        { "232-c1.c1",   0x800000, 0x5f8bf0a1, 3 | BRF_GRA },           //  3 Sprite data
        { "232-c2.c2",   0x800000, 0xe4d45c81, 3 | BRF_GRA },           //  4 
        { "232-c3.c3",   0x800000, 0x581d6618, 3 | BRF_GRA },           //  5 
        { "232-c4.c4",   0x800000, 0x49bb1e68, 3 | BRF_GRA },           //  6 
        { "232-c5.c5",   0x400000, 0x34fc4e51, 3 | BRF_GRA },           //  7 
        { "232-c6.c6",   0x400000, 0x4ff4d47b, 3 | BRF_GRA },           //  8 

        { "232-m1.m1",   0x020000, 0x45348747, 4 | BRF_ESS | BRF_PRG }, //  9 Z80 code

        { "232-v1.v1",   0x400000, 0x22a2b5b5, 5 | BRF_SND },           // 10 Sound data
        { "232-v2.v2",   0x400000, 0x2304e744, 5 | BRF_SND },           // 11 
        { "232-v3.v3",   0x400000, 0x759eb954, 5 | BRF_SND },           // 12 
};

STDROMPICKEXT(kof97pm, kof97pm, neogeo)
STD_ROM_FN(kof97pm)

static void kof97pmCallback()
{
        lans2004_sx_decode();
}

static INT32 kof97pmInit()
{
        NeoCallbackActive->pInitialise = kof97pmCallback;

        return NeoInit();
}

struct BurnDriver BurnDrvkof97pm = {
        "kof97pm", "kof97", "neogeo", NULL, "1997",
        "The King of Fighters '97 (Practice Mode)\0", NULL, "hack", "Neo Geo MVS",
        NULL, NULL, NULL, NULL,
        BDF_GAME_WORKING | BDF_CLONE | BDF_BOOTLEG, 2, HARDWARE_PREFIX_CARTRIDGE | HARDWARE_SNK_NEOGEO, GBF_VSFIGHT, FBF_KOF,
        NULL, kof97pmRomInfo, kof97pmRomName, NULL, NULL, NULL, NULL, neogeoInputInfo, neogeoDIPInfo,
        kof97pmInit, NeoExit, NeoFrame, NeoRender, NeoScan, &NeoRecalcPalette,
        0x1000, 304, 224, 4, 3
};

Did I miss anything important ?
And what do these codes mean exactly?

mitu

@ninja Are you running the game with fbneo directly or with lr-fbneo ?

ninja

@mitu lr-fbneo recompiled by myself

barbudreadmon

@ninja is there a reason for using a custom init ? it doesn't work if you call NeoInit directly instead of your custom kof97pmInit ? HBMAME is using standard init for that hack.
