In mode 2, Meka uses the mask derived from the lower bits of the pattern table register both for the pattern table and the color table. But AFAIK for the...
When loading a .sc file, Meka emulates 32 KB of RAM, mapped once (at 0x8000). However, AFAIK, the SC-3000 has just 2 KB of RAM mapped four times (at 0xc000,...
When loading a .sg file, Meka emulates 4 KB of RAM, mapped twice (at 0xc000 and 0xd000). However, AFAIK, the SG-1000 has just 1 KB of RAM mapped eight times...
