The video hookup is known to be wrong, cfr. accesses unmapped range $e80 in TMP68303F for a sprite DMA $300ff2 -> $b10000 note on top.

yeah maybe it's missing some dma for the attributes too then or something, at least this gets the rom loading and palette format out the way anyway.

It's the typical Seta "World" drawing, with 4 words containing pointers to GFX structures, sizes and colors.

Technically you can even fake the transfer by directly referencing the work RAM buffer instead.

yeah, sounds logical, so the tilemaps aren't really tilemaps, but large floating sprites, with the colour attribute in the list. Very weird to see a text layer done like that, but for these gambling games I guess they didn't really care.

I mostly just wanted to sort out the ROM load really anyway.
