Thanks for the feedback barbudreadmon. I'll be on the lookout for any new implementations. Best regards.
For example: TAITO_68KROM1_BYTESWAP32 / TAITO_68KROM1_BYTESWAP_JUMPING ...
These macros, which are actually numeric values, are converted from this text to numeric values when they are processed within the program.
Let's look at the definitions to see:
#define TAITO_68KROM1 1
#define TAITO_68KROM1_BYTESWAP 2
#define TAITO_68KROM1_BYTESWAP_JUMPING 3
#define TAITO_68KROM1_BYTESWAP32 4
...
So this is all we need to do now
{ "d67-19", 0x080000, 0x1d88fa5a, TAITO_68KROM1_BYTESWAP32 },
change to:
{ "d67-19", 0x080000, 0x1d88fa5a, 0x4},
It's that simple and there's no need for a big Copy and paste this content
romdata was designed with the idea of externalizing the game ROMs information, not creating anything extra.
