Sentinel 65X is primarily a tiles-and-sprites machine as far as graphics go, but it *does* support bitmap modes. You can even use the two layers for double-buffering, only enabling one at a time during VBLANK. The issue is that you only access VRAM through two 8-bit (or one 16-bit) registers in the I/O region, so copying bitmap data is a bit slower than if it were mapped right into main memory (a VERA variant that exposed the full memory would be fucking EPIC, mind you, but I don't think anyone's doing that project), so I don't actually know how well it would work. You'll have to try it and find out.
