Infocom V6 games using EGA and CGA graphics data

I've managed to replicate Kevin Bracey's work of extracting graphics data from Infocom's V6 games for MCGA graphics and put the results in a modern Blorb file. Tools are at https://gitlab.com/DavidGriffith/blorbtools. Now I'm trying to produce Blorb files containing EGA and CGA data. The EGA data ex...

Re: V6 Z-machine games cause assert() crashes

The problems you're having with the compass rose is that some images have an adaptive palette that changes according to whatever else is loaded at the time. You were right. With some extra logic to load the list and handle the palette copying, the Blorb version of Zork Zero now renders the compass ...

Re: V6 Z-machine games cause assert() crashes

The problems you're having with the compass rose is that some images have an adaptive palette that changes according to whatever else is loaded at the time. I'm currently flailing around with David Kinder's Windows Frotz code to figure out exactly how he implemented the palette changes and port it f...

Re: V6 Z-machine games cause assert() crashes

Andrew Plotkin's intent for Glk and Glulx was to breach the limitations of the VM being 16-bits and to do things Right (tm) where Infocom did things Wrong (tm). I seem to recall him describing Infocom's design for V6 as very kludgy at its very foundation. This led to inherent incompatibilities of Gl...

Re: V6 Z-machine games cause assert() crashes

Thanks. Now Zork Zero is loading properly, but the initial images using an adaptive palette are not rendered at all. This seems to be how Scummvm has been rendering the game with the original .mg1 file. Since I switched Frotz to using only Blorb instead of Infocom's audio and graphic files, it has b...

Re: V6 Z-machine games cause assert() crashes

I'm trying with the absolute latest from the repo. I then did a pull of the new changes. No change in crash messages. Checked out 9b7866442b477fe9376896fbf167622514700320 and got the same crashes. I have the game files as zork0.z6 and then the graphics are contained in zork0.blb. The blorb file come...

V6 Z-machine games cause assert() crashes

As my username suggests, I'm the custodian of Frotz these days. I'm trying to understand how Dreammaster added Frotz as a sub-engine of Scummvm, in particular how V6 games are handled and how to allow the player to highlight and copy text. These are two ongoing problems in getting the SDL interface ...

Grr... Another thing I should have checked more thoroughly. The solution is to start up DOSEMU and INSTALL the game. Then the correct files will be present.

Ringworld not recognized

I'm using the latest version of ScummVM and it doesn't seem to recognize "Ringworld: Revenge of the Patriarch". This was printed to the command line: The game in '/export/scumm/other/ring' seems to be unknown. Please, report the following data to the ScummVM team along with name of the gam...

LGOP2 opening the safe (debian squeeze)

This post started off as a cry for help, but I figured it out and am leaving some information for someone else who might have the same problem. If you're running Debian Squeeze and install scummvm from the standard repository, you'll most likely get version 1.1.1. This version has some sort of bug t...

Weird. I could have sworn that the spider puzzle was available at the very beginning of the game. At least that's how I remembered it back in 94. I'm using a different copy from the other one (now lost).

T7G missing the spider star puzzle

Could someone tell me why the spider star puzzle in 7th Guest appears to be missing? I'm quite sure I copied all the files available from both discs.

Running 1.2.1 on Ubuntu 10.10 installed from the .deb referenced from the ScummVM page.
