Re: WIP: VIC-2020 MINIMON cartridge

I operated MINIMON with one of my Mega-Carts for a comprehensive suite of tests. While doing so, I (re-)extracted the MC-specific version of TRON with a freeze reset: You could ask me :wink: With the page-wise ASCII memory display (one of MINIMON's transient tools) I also found a hidden game that a...

Re: 11 Vintage games from ALA Software (rare)

Hear hear, are you saying that I can actually mount and read TAP files with a standard SD2IEC device? I really didn't expect that :shock: Not for standard SD2IEC devices that use original sd2iec firmware, for what I know, only with C64SD Infinity+ITS module and newer version with patched firmware, ...

Re: 11 Vintage games from ALA Software (rare)

I don't think I can use TAP files on my SD2IEC. Yes you can if you have a C64SD Infinity or never, it uses both default sd2iec firmware or his custom firmware (sd2iec + XT IEC command that adds TAP support) To mount TAP file just use this command: OPEN15,8,15,"XT:FILE.TAP":CLOSE 15 Then h...

Re: How is one supposed to launch SJLOAD07?

Stressing not only means to let such a test running for a prolonged time. The timing could be at the brink and you might just be lucky to keep within the windows of the bit times at all times still. I explicitly meant to break the timing on purpose with an out-of-bound synchronisation delay and bit...

Re: help with VIA test prog needed

About my original curiosity about locations $9116 and $9117, I've tested 3 different unexpanded PAL Vic-20 and results are all different. My tests was, PEEK 37142 and 37143, Power OFF/ON, PEEK, Power OFF/ON, PEEK VIC1: PRINTPEEK(37142) = 255,255,255 PRINTPEEK(37143) = 255,255,255 VIC2: PRINTPEEK(371...

Re: How is one supposed to launch SJLOAD07?

I really would like to update my releases with a consolidated version pack of SJLOAD and would have no problems if it came as two separate binaries for PAL and NTSC. Don't worry, once I've succefully tested it also with pi1541 (both PAL and NTSC), I will find old sources and I will publish the new ...

Re: How is one supposed to launch SJLOAD07?

No. With SJLOAD07 (dating from 2010) and SJLOAD08 (the MC NVRAM version) there had been a somewhat unsound assumption it would work regardless which TV system, where actually the timing was correct for PAL only. SD2IEC devices seem to have a somewhat relaxed requirements. This is right for SJLOAD07...

Re: help with VIA test prog needed

I've briefly modified the code to add $A000 header but I don't know how to interpreter the screen results in vice. I've not checked the code but I guess it requires some modifies to run without any kernal initialization. In case, I have an hacked cart that works with a 27C64, It's easy for me to tes...

Re: BUY: PET style RETURN key

Welcome,

It's your first post, right?

I'm Italian too but all my Vics use the new layout, sorry. :(

What about a 3D printing custom part?

Re: help with VIA test prog needed

Very hard-core technical discussion here... :oops: I don't know if is the right place to ask but I have a 6522 VIA curiosity for the VIC-20 about locations $9116 (VIA1T1LL) and $9117 (VIA1T1LH), by using VICE the values for these locations are $FF $DF for both PAL and NTSC but I don't understand if,...

Re: How is one supposed to launch SJLOAD07?

I don't know this repository, someone just published the file in cc65 format posted by Diddl on forum64 in DASM format. For SJLOAD08, I remember that I've added a variable (PAL-NTSC) to compile also for NTSC with few differences but PAL output was the same. I'm sure I've used the 08 version for Mega...

DOOM Player

Hi,

Few months ago I "played" for a while with DOOM and using some source files, I've released just for fun a program for Vic+8K to play all DOOM musics with same look and feel of the original game.

I hope you like it.

PS: Like Doom use W S RETURN or Up/Down cursor key if you prefer.

Re: Diagnostic Tools for the Vic-20

Excellent! I was wondering how to use the dead test on a dead VIC in fact... Slapping it on the Mega Cart start menu will be great. I thought on this too, in effect as well as from the maintenance menu you can start the Diagnostic Tool and the Dead-Test also with a key combination on boot and if yo...

Re: Diagnostic Tools for the Vic-20

Unfortunately before the JMP(A000) the RESET routine ($FD22 ) run a subroutine: JSR $FD3F and this is a terrible point! yes right, in effect this is a problem, a faulty page 1 RAM may prevent to run any cartridge even if both DeadTest and Diagnostic do not use JSR call in the early stage but the ke...
