Some people has asked me how come it's possible to infect your PC via ZSNES using ROMs. Yes, it's actually possible. Like you can inject malicious code and make a malicious ROM file run like a EXE file when it's opened via ZSNES. Very dangerous stuff.
ZSNES is written in machine language - assembly (x86) and is solely focused in performance. This means that to achieve a better performance, some memory and location checks are ignored. These can be exploited, either accidentally when a game crashes or intentionally.

NEW SA-1 CHIP FINDINGS THREAD
This thread will contain all new SA-1 chip findings
Data verified on real hardware. Emulator authors should definitely keep in mind this information for updating the SA-1 emulation later.
1) Banks $50-$5F and $70-$7F are mapped on SA-1 CPU side.
$50-$5F is BW-RAM mirror. That means everything between banks $40 and $5F is BW-RAM. Does that mean SA-1 could map up to 2 *MEGABYTES* of RAM?
