ASM ROM header templates.
For cartridge systems
- $0064: VBlank handling routine pointer
- $0100: "NEO-GEO",$00 string
- $0108: NGH number
- $010A: ?
- $010E: pointer to debug DIPs (in user RAM)
- $0114: boot logo flag and tile number
- $0116: pointer to Japanese settings info block
- $011A: pointer to US settings info block
- $011E: pointer to Euro settings info block
- $0122: pointer to code start
- $0182: pointer to security code
Minimal header (from Smkdan's sources)
No need for a complete 68k vector table.
