It is a solution method of this problem?

in neo_run.cpp, at the end of unsigned short __fastcall neogeoReadWord(unsigned int sekAddress) is a return 0;
change it to return 0xff;

[DsNo]

In: neo_run.cpp

Code: [Select]

unsigned short __fastcall neogeoReadWord(unsigned int sekAddress)
{
switch (sekAddress) {
case 0x300000:
// bprintf(PRINT_NORMAL, _T(" -- bank %d inputP0[0x%02X] read.\n"), 0, nInputSelect);
return ~((NeoInputBank[nJoyport0[nInputSelect & 0x07]] << 8) | NeoInputBank[4]);
case 0x340000:
// bprintf(PRINT_NORMAL, _T(" -- bank %d inputP1[0x%02X] read.\n"), 0, nInputSelect);
return ~(NeoInputBank[nJoyport1[nInputSelect & 0x07]] << 8);
case 0x380000:
return ~(NeoInputBank[2] << 8);

case 0x3C0000:
case 0x3C0002:
case 0x3C000A:
// bprintf(PRINT_NORMAL, "  - Graphics RAM read (Bank %i, address 0x%04X).\n", NeoGraphicsRAMPointer > 0xFFFF ? 1 : 0, NeoGraphicsRAMPointer & 0xFFFF);
return *((unsigned short*)(NeoGraphicsRAMBank + NeoGraphicsRAMPointer));

case 0x3C0004:
// bprintf(PRINT_NORMAL, "  - Graphics RAM modulo read.\n");
return (unsigned short)(nNeoGraphicsModulo >> 1);

case 0x3C0006: { // Display status
// bprintf(PRINT_NORMAL, "  - Display status read, line: %3i, anim: %i\n", SekCurrentScanline(), nNeoSpriteFrame);

bForcePartialRender |= bForceUpdateOnStatusRead;

return ((SekCurrentScanline() + nScanlineOffset) << 7) | (nNeoSpriteFrame & 7);
}

// default:
// bprintf(PRINT_NORMAL, _T("  - 0x%08X read (word, PC: %08X)\n"), sekAddress, SekGetPC(-1));
}

// return 0;
return 0xff;
}

It fixed but it is identical as ever. It assists from Thank you.

Oops! I meant unsigned char __fastcall neogeoReadByte(unsigned int sekAddress)

It is perfect and it works! Thanks it gives with sincerity.
