Re: How to convert Tap files to D64?

The games themselves were not problematic, just the odd behavior of the combined files. It should have been a straight forward task - and usually is - to amend the loader, pointing BASIC to where the second part should reside. After the load has finished, point BASIC back to its usual starting place...

Re: 5 Ultra-Rare Games by "Aim Software"

Had a lot of unusual trouble converting these. Tried the .tap files and all seemed OK so made them all one-filers and saved to disk. Went through them all again and some wouldn't work. Then Butterfly refused to load from .tap so had to resort to files from Barney's converted disk. Tap Clean won't wo...

Re: Vicships - New Puzzle Game

......one year later!!! Although the instructions were on the disk, this seemed to confuse people as to what the game actually was. Vic-20-Ian was correct about it being a 'Pic-Cross' type puzzle. This was a popular puzzle printed in some UK newspapers, along with sudoku and the like. The puzzle was...

Re: 15 Vintage games from ALA Software (rare)

See if these work on the real hardware. All one filed on a .d64.
There were a couple that started off OK but went into NTSC land when restarting, so I fixed them to be PAL/NTSC friendly.
Enjoy.

No.

I've one-filed the +3k version for you to include if you so wish.

Re: Bad myriad 8k version

It seems that this one-file version does not zero the high-score upon initialization.
I've hacked the code so that it does.

New file in original post.

Bad myriad 8k version

I watched OldSkoolCoder do this: Tutorial 38 : Ep 01 - Reverse Engineer Myriad VIC 20 (6502) and saw that the graphics in the game were corrupted. I checked my 3k version and it was fine. I checked the 8k version from zimmers and the one in GameBase 20; both showed signs of corruption. Bad text .......

Re: Unpublished Italian game: SATURN CAVES arcade adventure

There was only 7 bits of data in line 204 which caused all the graphics after this line to be corrupted.
I fixed this and tried the game and it looks OK now (fingers crossed).

Re: Unpublished Italian game: SATURN CAVES arcade adventure

I'm taking a look at the graphics, but without knowing what they should look like, it's a bit of a grind.

One thing I can rule out are lines 136 and 137 of listing 2.
These represent the characters % and $ and are correct.

Fixed line 425 'elixir'.
Fixed line 3691 graphics.
