SRAM/WRAM Support for Compo Entries

Post by Goose2k »

Is there any SRAM/WRAM available for game competition entries? If so, will it have save/battery-backup support?

On the Mapper 28 page it says:

"Adding WRAM control requires 2 Macrocells and 2 pins."

Historically, no. I recall tepples talking about exposing a simple API for save games in a couple Flash sectors, but as far as I know that wasn't implemented for lack of interest.

On the Discord, Tepples says:

"Compo entries can't use WRAM at $6000. If you run low, you can use otherwise unused CHR RAM as WRAM by reading it and writing it through the PPU's video memory interface."
