Your wish is my command :wink: Here is "planetfall" and the sequel "stationfall".

Re: Bitshifter's Z-code interpreter

Here's now the (first :wink: ) final release of my Z interpreter together with the Zork trilogy as example stories.
Have fun with these famous adventures of the previous millenium. :D

Re: Bitshifter's Z-code interpreter

I had no feedback during the last two months, so I think I should release the current version of the interpreter.
Together with some story files, the Zork trilogy, and then Deadline, Suspect and Witness.
I'll do some final tests before.
まで来週

Re: RAM expansion cross-talk issues

I did that much manually and got: 14,14,14,14,170,170,86,87,88,13,85,85,85,85,13,170 Oh! That looks like timing is on the brink indeed! For some bytes (notably those with 14 and 13) it looks like you get the original/intended data (or the original data is retained), and the values 170 and those aro...

Re: RAM expansion cross-talk issues

Hi Bit Shifter, I can confirm that your new "almost final" trilogy release doesn't work the my Mega-Cart expansion (not a surprise). I just wanted to say, though, that your port is a very beautiful presentation. The font and 32 column choice is very nice looking. I like the way you can no...

Re: Bitshifter's Z-code interpreter

I looked, wether I could spare the 3K memory range of $0400-$0FFF, but that would cut the disk cache section into half the size and make it too tiny to be useful. So I left the memory layout as it is, hoping that the +35K memory requirement is not too restrictive. Here's now the new version of the Z...

Re: RAM expansion cross-talk issues

Well, good news. With the UltiMEM, both ZORK and the Mike's panning viewer work. So I guess that the Mega-Cart's 32K+3K (35K) is not functional? As for beta-testing this ZORK 32-column version: I was able to load both Zork I and Zork II (didn't try Zork III). I moved around a bit and was able to ex...

Re: RAM expansion cross-talk issues

Would the fact my uIEC is set to device 10 instead of 8 be a problem? I didn't see any attempt to access Drive 8, though. No, the device number isn't a problem. The program uses the device number, that was used to load the program. But I think, I found the issue: The program scans the whole story f...

Re: RAM expansion cross-talk issues

That's a pity :( Error codes 1 and 4 indicate, that's something wrong with the story file. 1 is for bad (z-code) operand and 4 for bad (z-code) opcode. On real floppy drives, I would guess, it's a read error, but on SD2IEC this shouldn't happen. Unfortunately I have no real VIC and do all testing wi...

Re: Bitshifter's Z-code interpreter

You need a VIC (or an emulator setting) with 40K ! 32K is not enough, there must also be RAM in the block 5 ($A000-$BFFF). "+32K" is commonly referred to as the RAM configuration with RAM in BLK1..3 and BLK5. If you also use the 3K in the address range $0400..$0FFF (like Kweepa did with V...

Hi, Bit Shifter! It's nice to see your Z-code interpreter is going to have an 'official' release at last. :D @Bit Shifter: Welcome to Denial! :mrgreen: Michael Thanks Michael. I didn't know this cometfall version, it seems, that someone had similar ideas. It will also prepare a cometfall image, it ...

Re: Bitshifter's Z-code interpreter

Welcome! Good to see you are carrying on this project! The proportional font looks nice. Maybe you could drop the letters with descenders down a couple of pixels like this: https://www.youtube.com/watch?v=w_bgobRphlw :) We already had a long font discussion at "forum64.de". There was no a...
