It's not a texture cache, it's 4KB of texture memory that needs to be manually babysat both in an emulator and hardware.

- rasz 3y agoIt might be the same situation as with Atari Jaguar where silicon bug turned texture cache into a fixed buffer you have to load manually.
- mikepavone 3y agoAFAIK, the memory inside the Tom chip was never a cache. The bug you're probably thinking of is one that makes it difficult to run code on Tom's RISC core directly from main RAM. IIRC, jump instructions are pretty bugged when not running from internal RAM, but the homebrew community came up with a workaround. It's still not acting as a cache in that case though. It just fetches instructions from RAM as it goes.
- monocasa 3y agoIt's not.
