Denial

somehow seeing ppl arguing over this trivial stuff is cute <3

all it takes for VICE to support it is a link to the cartridge image...

jesus =) i have converted it to acme, see https://sourceforge.net/p/vice-emu/code/34291/

shows a straight line

nice little program.... would you post the source too? i'd like to throw it into the VICE testprograms repo...

Honestly, where ? The OP only said...

you did not reply to the OP, you replied to ME.

AFAIK, the vast majority of people using RAM expansion on their VIC-20 do it with a cartridge, not a hardware mod.

thanks, captain obvious

what about "no interested in hw mods" was not clear? OBVIOUSLY you can achieve all kind of things that "do not work" by modding the hardware. Of course it's not all that sensible to modify the mainboard if the intended result could also be achieved by an external solution. i don'...

i like how that thread (once again) derailed =)

i am not really interested in solutions that involve modding the hardware though... obviously then its possible (or i could just pop a custom rom into it...)

it would be so nice if you could map the e000-ffff block to ram as you can on c64.... but you cant

the ROM _does_ use decimal mode at least...

btw, the upcoming micromys v5 adapter will do 1531-alike mouse for vic20

yeah right at startup (it doesnt quite start that is )

Are you sure? I've got my emulator working now. At the start of the game, it appears to set the following: oh! interesting :) i must have somehow missed that in the process... i had to add some of my own init stuff to make it not show crap at least :) your emu crashes on me though :( $ java -jar at...

I don't think the control registers themselves have intended default values on startup of the chip.

at least some of them must have defined default values - else this game would show random garbage

the game does very few actual accesses to the VIC, so its almost useless to tell the differences by looking at the game code... one thing that is obvious though is that the defaults differ :) meanwhile, i have it kinda working without a patched kernal.... the monkey patched screen copying stuff make...
