Re: Using Exomizer

This is the way I did one-file my "Cheese and Onion"-cart back in 2017: 1. Crunch just $2000-$7fff version as sfx-archive 2. attach $a000-$bfff-file at the end of that file 3. change the BASIC-sys to a new routine at the end of the combined file 4. use small assembler-routine at that new a...

Re: modded VIC 20 kernals?

True, running Minimon in $9800..$9FFF certainly is a nice trick. :) However, the disadvantage is that it needs an additional cartridge which is blocking the expansion port, so you will also need an expander. No, it does not, the cartridge port is extended on the MINIMON-cartridge: http://sleepingel...

Re: In the making: Arukanoido – an Arkanoid clone

Thanks mate! Arukanoido is already much better than anyone could ever have hoped for! So if this is the "final version", so be it.
Here's hoping for better times. VIC-20 coding should be for fun :D

Re: In the making: Arukanoido – an Arkanoid clone

Thank you for all your hard work on this! Can someone compile and provide a binary provided that's ok with you, of course? I can see that a physcial release is a pain to do with small rewards. Also regarding the copyright issue I think this would stir things up unnecessarily. I guess most publishers...

Re: modded VIC 20 kernals?

If I had one mod for the VIC KERNAL, it would be to amend the screen routines to take account of variable dimensions instead of relying on the hardcoded values... :P You do not need a new kernal for that: http://sleepingelephant.com/ipw-web/bulletin/bb/viewtopic.php?t=8375 Apart from that, I don't ...

Re: How do I redefine characters with 8k or more RAM?

You seem to be going in the right direction, but it seems you still do not understand a few basic concepts: POKE44,22:POKE7168,0:NEW If you want to redefine 256 characters starting from 5120, you will need to protect 2048 bytes from BASIC access from 5120 onwards (= up to memory location 7167). As s...

Re: ELITE

This bring me back to my very first post on Denial . Basically I think the bitmap would pose no real problem. The viewport could just be 128x144 pixels (half the res of C64) and if you keep the instruments monochrome (like the Electron version) they can use another 128x56 pixels as demonstrated in m...

Re: Give me all your pocket money! (For tapes, that is.)

While I am a fan of physical releases, I'm not really a fan of tapes. Also, on the physical releases I own I still use the digital version (either in emulation or through SD2IEC-drive on the VIC). But anything that is a cool project and/or looks cool in the cupboard will get my money. Unless it's un...

Re: In the making: Arukanoido – an Arkanoid clone

Saving to disk would require a file selection, wouldn't it? I have no experience with saving scores. Not really. If you alyways use the same filename like "hiscore", you could just load it in on startup (from last used device = $ba) and delete and save it under the same name after a playe...

I never understood why most Arcade-conversions go to the trouble of emulating the annoying high-score input by joystick which is just done this way on the Arcade-machines because they have no keyboard. By the way: Is the high-score table saved to disk?

Yes, I send my updates to Richard regularly. But, downloading a zip-file should usually not trigger a firewall. Unless you are in a business-enviorenment with very strict restrictions.

Re: VIC20 with NOS 6561 sound problem

I had a VIC-chip as well that was defective on bit 3 of the volume-register. This went in to the bin, luckily I had replacements back then. I agree that the defect is subtle and you only notice it with certain games/demos. But still it is a defect.
