Hi Demo Maniacs.

I am curious whats up with that Demo.
https://www.pouet.net/prod.php?which=3400

[ Show youtube player ]


It should run on every AGA Amiga with 8MB Fast-Ram; but it stops in the middle of the Demo on a black screen;
Music keeps on playing.


Tried various things; no luck so far. Hmmm.
Why ? Any Ideas ?

Hmm a dirty hotfix or Whdload slave would be great

Did you try a configuration with FPU activated ?

[paraj]

Doesn't need FPU, but rather seems like a timing thing.

What system are you running it on? If it's WinUAE try 040 instead of 020/030 and/or "cycle exact mode".

Don't feel like debugging it, but seems like it gets stuck in some loop that you can just break out of

[Torti-the-Smurf]

Usually i use a 68020 Setup in Fpga, same in Winuae.
It does work in 040 uae; not on Mister & Stuff, you know.

Such a nice demo of Haujobb.

[paraj]

Guess I can see if it can be easily patched. I have neither Mister FPGA nor whatever you mean by "stuff", so will have to assume if it works on WinUAE 020/8MB it'll also work there. ("Only" have 060 and pistorm A1200's to test on, and it works there).

[Torti-the-Smurf]

Works in WinUae in 040 mode; but it shouldn´t need the 040. hmmmm

A fix would make this Demo more accessible, for all those various systems. *below*

i Could test it on MiniMig Fpga (Mist).

Stuff, means (4me), other Amiga Configs, other Fpga´s, various real hardware setups, various Emulators/configs n´ so.

that work well here in 030 + fpu , cycle exact, 4mb chip and 32mb z3 fast, cpu frequency x8 in CLI mode with last version of winuae for info

[kriz]

Always seen it as a 060 demo as it was released @ Mekka Symp 99.. Still rulez but 020/030 will be too slow for this in full speed i think ..

[Torti-the-Smurf]

Runs pretty much fullspeed on a fast 68020 & 030 system with "fast" Fast-Ram.

My 68020 FPGA setup has (Sysinfo test)
Dhrystones: 12800
Mips: 13,33
ChipSpeed vs 600: 27

Runs pretty much all the 2x2 C2P Stuff in fullspeed.

Same with this Demo; but stucks on a black screen at the middlepart
A bug, like Paraj said.

[paraj]

Try this with the "Force use of CPU C2P" option enabled. Place mathtrans.library and the demo executable next to the slave.

[Torti-the-Smurf]

Works great now!

Thank you so very much paraj
