ROM Version Differences

Retail Versions

The differences between the two retail versions (v0 and v1) of E-SWAT include:

  1. In v1, the function at $08a9 which reads from VRAM adds two extra opcodes for delay purposes [1]. One of them is unnecessary, the other increases the delay between VRAM access from 18 cycles (too little) to 25. This bug fix confirms that v1 is a later version than v0.
  2. v0 does not have a timer at the continue screen, while v1 does.
  3. In v0, the player's health replenishes on reaching a boss, which it does not in v1.
  4. v1 gives the player significantly fewer bullets than v0.
  5. v0 has an "Arrest" graphic at the bottom of the Round Start screen.
