TODO:
- Find source of level 2 interrupt (sprite DMA end?)
- Decrypt newer games;
- Find source of level 2 interrupt (sprite DMA end?);
- magibomb: fix timings;
- astoneag: finish program ROM decryption;
- astoneag, magibombd: currently stop during with 'ROM error'. The first few hundred bytes don't decrypt correctly,
it it suspected there's a ROM overlay provided by the protection device;
- winbingo and clones, zulu: these should be at the same state of the two above, but don't show anything on screen;
- magibomba, westvent: need a redump of one of the program ROMs;
- dinodino: not decrypted yet.
