Re: Attack UFO - Arcade game that uses the 6560

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

Re: GeoRAM on the Vic20

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...

Re: Attack UFO - Arcade game that uses the 6560

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

Re: VIC Game Club No. 11 – Paddle Games

Re: HASL for cartridges? (split/OT from: Cheese & Onion)

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...

Re: HASL for cartridges? (split/OT from: Cheese & Onion)

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...

Re: HASL for cartridges? (split/OT from: Cheese & Onion)

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...

Re: New physical cartridge release: Cheese And Onion

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...

Re: New physical cartridge release: Cheese And Onion

it wont cause any serious damage... perhaps the contacts corrode a bit (because of the different metals) but thats all (and it can be fixed/cleaned easily). back in the days tons of cartridges existed that didnt have gold plated contacts, and you didnt see machines dying left and right because of th...

Re: PC COM port to Vic interfacing

*shrug* how you connect them depends on their logic =P you cross rts/cts for nullmodem, but thats probably not what you got there. it makes sense to have only one of the two (the PC is kinda infinitely fast, the other side may be slow), but i forgot which goes in which direction =P
