Ported Dungeon Master Chaos Strikes Back to Web-Based

[sephirothvr]

I manage to port over Dungeon Master Chaos Strikes Back to web-based.

• Using DSB Source Codes

• Using Chaos Strikes Back for DSB with Character Selection Level and button to jump to game

• Running on chrome, safari, edge.

Try out now and let me know if there's any issues. I tested so far okay, but didnt fully test till end of the game.

Pretty impressive!
Looks like you added a new text renderer?
The party icons layered rendering is busted, but most of the UI seems to work OK.
Unfortunately my browser crashed while walking around the first worm room. Latest Chrome on MacOS Sequoia.
I can supply the full error dump if you need it, here's the summary:

Updated the game with the following changes.

• Fixed retained bitmap/canvas resources that could exhaust browser graphics memory.

• Replaced the original front menu with the new CSB prison-style PRISON/RESUME menu.

• Reused released bitmap handles instead of continuously growing them.

• Reworked party-icon layering to avoid temporary canvases while preserving transparency.

• Added Intro Movie for the game’s opening video.

• Centred the champion’s name correctly inside the spell panel.

• Removed the hidden walls leading to the Original DM champion selections area.

• Added contextual instructions at the dungeon-start button.

• Prevented entering the main dungeon without selecting at least one champion.

• Repaired the missing diamond marker beside PRISON.

• Prevented the introduction video from replaying after game over.

• Added looping dungeon.mp3 ambient sound at 25% volume.

I throw my hat into the ring Ok the intro is missing, Full DM1 running on WASM (can be played also from desktop with python):

I will implement a language selection and also the CSB and a better way to handle right mouse button for touch displays.

But at the moment im crunching DM2.
