Re: Diagnostic Tools for the Vic-20

I didn't realise that the Mega-Cart firmware was updatable? No it's not actually, this is my prototype board, I'm testing the new firmware revision 22 which will be used for the next Mega-Cart shipped by 6502dude but I'm working also on a new external menu for older Mega-Cart revisions that allow t...

Re: Diagnostic Tools for the Vic-20

I was planning to make my dead test support being an EPROM inserted as a replacement for the KERNAL ROM. That way it is usable even when the system is unable to boot to an external cart. Running an image in BLK5 requires a (short) bit of code in the KERNAL, if it's defective you can't start anythin...

Re: Trained VIC20 Games , Cheatcodes and Trainer Pokes

By using the Miklós PAL/NTSC intro screen, I've released a new Frogger '07 version with a nice additional cheats (fire to freeze).

I really dreamed this function when I played Frogger from the arcade cabinet :D

Re: Diagnostic Tools for the Vic-20

I'm happy that could be useful for you.

I will include these tools also on the new Mega-Cart external SD menu that I'm releasing.

It will be a sort of extension/addon for any Mega-Cart revision + SD2IEC drive.

Diagnostic Tools for the Vic-20

Hi everybody, Time passes and our beloved Vic-20 begin to age... I had a problem with a my VIC so by searching on the net I've noticed there is a lot of interest on diagnostic tools (software and hardware) but for a reason or for another nothing sodisfied me. At the end, I've written some Diagnostic...

I have been away for a while and in the meantime I have lost this pearl ! I think that now is perfect, is the best Space invaders conver...

Re: Sport sport PAL to NTSC

Sport Sport 2002 PAL - NTSC 8k I must say that Miklós made a really big work, in spite of what it may seem, this is not a "simple" PAL/NTSC fix but all the NTSC portion is practically all rewritten. Very good job, my compliments! Even if I'm in the final phase, It deserves a place in the ...

Re: Two new games for the 8k Expanded Vic - 2022

thanks for sharing, you are really "prolific" :wink:


PS: I've noticed that both games start from $1200 and you have to load them by using LOAD"GAME",8,1 I think is better they start from $1201 so you may load them even with a simple LOAD"GAME",8

Re: ** New Frontiers in VIC-Hires-Graphics, Part 16

Here are another two images I converted to 104x256 Wide FLI (PAL, +24K RAM required): Wow, Really impressive! I've attached a modified Vic20-Ian version with new Mike's images. I don't have a TheVic20 but should work, with VICE and real PAL Vic works. The modifies are: -d64 -> d81 format to include...

Re: How is one supposed to launch SJLOAD07?

Just an SD2IEC-device. This may explain why you didn't have problems. I don't know how much the NTSC emulation of VICE 3.6.1 is accurate but using the SJLOAD07 to load items from a Vic-20 NTSC with 1541-II+JiffyDOS drive produce a ?FILE NOT FOUND error while seems that the 1581+JiffyDOS works anywa...

Re: How is one supposed to launch SJLOAD07?

To be honest, my installed PAL-version of SJLOAD08 on the MegaCart works fine on my NTSC-VIC as well. At least I never noticed a problem. Do you use a 1541/1571/1581 drive + Jiffy ROM or a sd2iec device? Maybe the sd2iec firmware is much more timing tolerant then the original JiffyRom for the CBM d...

Re: Space Invaders / Connect-4

Yes, I'm not very happy with that sound. It is one of the key things of the game and, in the arcade, sounds much better. Will try to improve it. Take "inspiration" from Alien Blitz Regarding the volume I don't think I can do too much, since modifying the volume for missiles will also affe...

Re: Space Invaders / Connect-4

Speaking of sounds, the arcade sound for alien footsteps is a bit longer and has 4 different notes (similar to alien blitz) while your version uses 2 notes only. The missile sound is a little bit less acute and volume a bit more low. PS: I suggest to start 1 player game also with fire from title scr...
