The speed of the enemies is faster in the first part of this version than in the original game (and Xuel's NTSC version). I'm not sure how the rest of the game compares, as I didn't play through much of this version yet.
Yeah I noticed that too. The reason is that Rambo Blade replaces the LDA VCOUNT / BNE with LDA VCOUNT / BEQ which effectively gets rid of the frame syncing altogether. This means if you run on a 65816 at a higher frequency (e.g. 21MHz), then the enemies are super fast.
Other than that difference, it's interesting that Rambo Blade uses a similar NTSC-fixing strategy to the one I employed with Joe Blade II, i.e. just swap the immediate and deferred vertical blank routines instead of moving both into deferred as I did with Joe Blade.
