Target

Mapped ROM program

You can create program using one of this supported ROM mappers:

• ASCII-8: 8KB segments for a total to 64KB to 2MB,
• ASCII-16: 16KB segments for a total to 64KB to 4MB,
• Konami: 8KB segments for a total to 64KB to 2MB,
• Konami SCC: 8KB segments for a total to 64KB to 2MB.

In your build.bat, chose as target on of the following type: ROM_ASCII8, ROM_ASCII16, ROM_KONAMI, ROM_KONAMI_SCC. You can specify the ROM size (in KB) in the ROMSize variable. Default value is 128 (KB). Any multiple value of the mapper's segments size is valid, but I recommend using powers of 2 values (64, 128, 256, etc.) to help emulators to autodetect the right mapper.

Some Build Tool configuration examples:

REM -- 128KB ASCII-8 mapped-ROM
target=ROM_ASCII8

REM -- 4MB ASCII-16 mapped-ROM
target=ROM_ASCII16
ROMSize=4096

REM -- 512KB Konami SCC mapped-ROM
target=ROM_KONAMI_SCC
ROMSize=512

See s_vgm sample for a concrete use case.
