iNES Mapper 098 has been earmarked for an in-development mapper intended to make GBC -> NES ports easier with modest hardware manufacturing costs.
Exact hardware specs are yet-to-be-finalized. But key features include:
- UNROM-style bankswitching with support for up to 4MB flash ROM, optionally self-flashable
- 32kB of CHR-RAM, divided into 4kB pages
- Optional support for up to 32kB of switchable PRG-RAM
- 8x8 color attributes (8x1 achievable with raster tricks)
- Cheap scanline IRQ partially driven by software
- 4-screen layout using parts of CHR-RAM, or 2/1-screen layout using CIRAM
