nds显示部分2d能力不行,无法完美模拟sfc,哪怕是不带特殊芯片的游戏rom.

FluBBa说的:
The problem with priorities is that all tiles in 1 layer can have 2 different priorities.
The biggest problem with "transparency" is the subtractive blending.  
Mode 7 rotation is not a problem per se, HBlank DMA is.

sfc的3个特性难模拟,一个是bg layer里的title优先级,一个subtractive blending,一个HDMA.
前两个不完美,画面混乱,后面一个不完美,游戏crash.

其实无论是snesDS还是这个snezziDS,目前表现都是已经利用gba那个snesadvance的hack数据来优化过了.
