@ -158,25 +158,11 @@ Stephh's notes (based on the games M6502 code and some tests) :
for the "shoot" stages instead of 5.
- Continue play is always available and score is NOT reset to 0.
3) 'wexpressb1'
- "@ 1986 DATA EAST CORPORATION" + no code to display the Warning screen (World)
- This version is based on 'exprrada' so all comments also fit
for this set. The main difference is that reads from 0x2800
and 0x2801 (protection) are either discarded (jumps are noped
or patched) or changed to read what shall be the correct value
(reads from 0x2801 occur almost all the time).
So IMO this set looks like a World bootleg .
4) 'wexpressb2'
3) 'wexpress'
- "@ 1986 DATA EAST CORPORATION" + extra code to display the Warning screen (Japan)
- Modified Warning screen
- This version is heavily based on 'exprrad' (even if I think
that there shall exist a "better" Japan undumped version)
- This version is heavily based on 'exprrad'
so all comments also fit for this set. The main difference is
the way protection is bypassed (in a different way than 'wexpressb1'
as reads from 0x2801 only occur when a life is lost).
The other difference is that you can NOT continue a game.
- "Bonus lives" routine starts at 0xe4e5.
- Coinage related stuff starts at 0xe7d8.
