I had this same doubt.. I thought the screen virtual area 64x64 was standard for mega drive.Stef wrote: ↑Tue Jan 16, 2018 1:00 pmTo release some VRAM in the tilemap allocation.
Megadrive allow 32x32, 32x64, 64x32 (default since SGDK 1.31), 64x64 (defaut in SGDK < 1.31), 128x32, 32x128 tilemap size
But almost time 64x32 is enough to do whatever you want and allow to store more tile data in VRAM =)
Of course you can change the VRAM setup if you want =)
Nice to know about it.
