I remember playing River Raid back in 1998 or so on an emulator and using a hack for unlimited lives or invincibility or something. I do remember the river repeating several times before I got to !!!!!!. So, I'm a bit confused by this thread where folks are saying it is random and doesn't repeat.

So I guess this answers the questions others have had then... is it at level 57338 that the game goes haywire?

No, it just repeats.

Perhaps I'm misunderstanding what is meant by "levels." This doesn't mean bridge to bridge, does it? Because I didn't think it took that long at all to make it repeat.

From my River Raid disassembly:

Section generation:
; The river is divided into sections which are generated by random. The random
; number generator can generate 57337 different sections. Each section is
; divided into 16 blocks. The last block is the bridge. For each other block a
; random Id is generated, which defines the shape of the river. The river is
; randomly generated with or without islands.
; Each block is 32 lines high...

I'm not sure off the top of my head how many screens that amounts to. Does this mean all 57337 combinations get used, being "random?" Or, does it not use all 57337 and start repeating before that?

I guess another topic for hacks. Change the code so that the score / game does not crash. There would be many candidates for this fix.

No, you don't. Only the score is set to !!!!!! when you passed 999990 points and the game stops.

Fake yes, but TOTALLY fake, or is there a ROM out there?
