>had half the VRAM removed at the last minute I've never heard anything suggesting that video RAM was removed. AFAIK, the SNES was planned to have only 8KB of main RAM, which was increased to 128KB by release. I think any support for 128KB VRAM was for future proofing, like if the SNES's hardware was reused for arcade systems, or something. Source:

The Genesis's video chip can support 128KB video RAM as well, which besides allowing a larger variety of tiles on screen and doubles DMA bandwidth. It was used in the System C2 arcade board. The Genesis was originally designed to use 64KB video RAM, but after hearing about the SNES, support for 128KB was added. Then they decided that the extra RAM didn't make enough of a difference to justify the cost, so they left it at 64KB. Source: https://readonlymemory.vg/shop/book/sega-mega-drive-genesis-... |
