so far what i have done is hooking into a routine that gets called once per frame, and then i just copy the screen (and color ram) to some location that is suitable for vic20 :) changing the addresses in the program is certainly possible too... but as said, a lot of work, since its not really obviou...

rotating everything would basically mean rewriting the game, i am certainly not attempting this :) actually, even making it work on actual vic20 without the terrible hacks i have been using (eg i modified kernal) seems difficult without putting a lot of effort into it but yes, controls work, it can ...

i was interpreting some things wrong :) this game uses some really unusual programming techniques (which unfortunately will make it quite some work to patch :/) i have it "running" now ... in the sense that i can start the code, it runs and doesnt crash, and i can see the rendered screen i...

LOL

found it

is it for certain that it uses a 6502 and not 65C02 or other derivate? if its really 6502, then there is quite a bit of "illegal" opcode usage =P

just let it go...

and share some of that popcorn will ya?

I'm a bit dubious about the VICE implementation, since seems to be mapping three GeoRAM across both I/O slots. three? how three? *shrug* it maps the registers into the IO2 area (dffe/ff - with mirrors across the whole page due to incomplete decoding) and the actual RAM page into IO1 (dexx). nothing...

is a ROM dump around for this? would be a fun hacking project (to try making it run on the vic20)

don't bother, he won't let it go

oh, my bad. i mixed it up with the C64 version of sea wolf (which is often listed to support paddles - but apparently doesnt work with paddles at all)

how do you activate paddle support in sea wolf?

Haven't tried but I guess spraying the port and a cart with switch cleaner and then inserting a few times would also work. those magic cleaner solutions are almost always a bad idea (if used like this) - they will dissolve the oxide perhaps.... but then you will rub and spread it all over the conta...

if you are scared of sandpaper and think it will damage your sanity... just use a piece of thick cardboard. takes longer, works the same. no big deal whatsoever. you could even wrap a piece of cotton around it and soak it in IPA. (using a tootbrush like someone else suggested would also work well, h...

using sandpaper in any female edge connector will grind off the gold plating in it. Also, if you blow on the stuff you grinded, there is no telling where this conductive material will land, possibly causing all sorts of damage inside your VIC. you use fine grained sand paper and dont apply a lot of...

I know of absolutely no way of cleaning the cartridge port connector of a VIC-20. you are surprising in multiple ways, every time. its not rocket science really: you take a piece of cardboard or wood or plastic or whatever else you have laying around that fits between the contact, wrap a piece of f...
