CPS2 rom layout

Graphics Layout

all this information is to-be-confirmed..

CPS2 has, depending on PAL, up to 32mb of graphics. When using eproms, this space is split into two chunks. The lower chunk, and the higher chunk.

• Lower chunk consists of eproms 13,15,17,19
• Higher chunk consists of eproms 14,16,18,20

The eproms of each chunk is interleaved, so while the GFX eproms may be of different size, they are always the same size within each chunk. Some games only use one chunk, either the higher or lower.

• When using F and G PAL, the split is at 16mb (half of 32mb)
• When using B pal, the split is at 8mb (half of 16mb)
• PAL D & E is not known
