Bitshifter's Z-code interpreter

[orion70]

Wow! Thanks a lot
Will download tomorrow!

It looks like the <MORE> routine scrolls one line more than it should, perhaps because it's not accounting for the status line?

From the Witness intro:

But there's a missing line of text, which scrolls by but is then blotted out by the status line:

"windows are full of light, and radio"

I think I fixed the <MORE> problem with a little hack. If anyone wants to test it:

witnessHAX.d64.zip

Looks like that worked!

The same off-by-one error also affects the C64 version, presumably the others as well.

(To generate a ton of text in the early going, you can do

n.n.ring bell.read scroll

That will be enough to give even the compact font on the C64 version a run for its money.)

Bitshifter, thanks sooo much for all this excellent work. I am downloading everything again (including the Witness corrected version) for my updated SD2IEC collection. So once more, this is a good moment to ask: any chance to see Sherlock, which is my favorite Infocom adventure, in a VIC incarnation? Too much memory required? I know you worked from scratch compared to previous efforts (TNT's and the German team's versions), maybe you can find the way to squeeze everything in a 32K VIC? TIA

Bitshifter: If you want to save memory on the font, I have code that takes the internal char ROM to make 6-bit wide characters that are readable. I can send you the code if you want to test it out.

Anyone knows if the Z-code interpreter source was made available?

Hey, interesting! Thanks for pointing it out

Hello all! I am the author of the aforementioned text adventure, that uses Bitshifter's wonderful interpreter (thank you!).

The game has been released for 36 different platforms, among which the VIC-20. You can find it at hlabrande.itch.io/tristam-island. The game comes with a hint sheet and a feelie (a postcard set in the game's universe); it's around 7-10 hours of gameplay. I posted more information in the thread of 2020 releases. Thank you!
