I've noticed you changed the character select cursor to a solid block. While this makes it easier to spot which character had been selected, I guess inverting the character below the cursor might even look better. My second point is more of a design issue. The characters making up the frames don't ...

Obtaining the size of a file on disk

I'm attempting to obtain the size of a disk file in bytes before it is processed. Unfortunately my knowledge of Commodore DOS is still quite poor. :roll: Apart from opening a file and reading it byte by byte and keeping a counter until EOF is reached, is there a quicker way to get the exact size in ...

I'd always assume that kernel functions use all registers. There are not many registers in a 6502 anyway. You could have a look into the ROM listing or step into the routine using a debugger to see what's happening. yes! In case of GETIN function: If GETIN uses keyboard: - if no key pressed (empty ...

Question about Kernal function GETIN $FFE4

According to the PRG registers affected by this are A and X.

I seem to be getting corruption of Y register after calling this. :?

Is the PRG incorrect?

WTB: VIC 20 Programmers Reference Guide + Hardware

I have do an PDF version of the PRG. But seeing as I'm still a novice where the VIC is concerened, I do have to refer to it quite a lot and it's a real pain not having a real copy to thumb through when needed. So if you have one for sale, send me a PM with the £££ your asking including P & P - f...

Changed colour scheme closer to original one used. The vertical bar between character display, and clipboard is still in red. ;) x = Exit Application (with confirmation) - Soft reset. SYS64818 is a faster alternative. It omits the RAM check, which mainly serves to determine the amount of available ...

Also added some colour - some feedback [...] would be nice - as I have noticed some colours don't always go well together if not using an S-Video mod. There are five groups of colours with similar luminances, i.e. essential *no* contrast on a B/W monitor or TV: - Black, - Red, Blue, - Green, Purple...

Better :lol: One question: Do all these character sets have only changed characters in the first bank? When I switch between banks it seems that none of the test fonts have changed bank2. Another thing: After loading and examining some fonts I wanted to go back to the standard font as a basis to st...
