Vroom on A1200

[john1979]

On Whdload+A1200 I found adding nocache makes vroom work without the corrupted grpahics.

Thanks john1979, but i don't uses Whdload. My thread was opened concerning an AGA cracked floppy version of vroom . Any news about this by the way ?

This game I just tried. Simply stunning racing game!
As talked about in this thread it seams like there could be a fix for faster amigas?
When the game runs on 030 there are quite some gfx corruption.

Thankfully I have 68000/14MHz where it runs perfect but 030 seams like the sweet spot.
Anyone interested in looking into it?

This game was fixed in 2006 by Mr. Lamer. The WHD slave 1.4 works fine on 030. Please update your slave.

It works fine must be the right word, cause it is just fine.
There are a lot of gfx glitches.

I found on an ancient cd this file

F1vmultiplayer.DMS VROOM MULTIPLAYER AGA/ECS 1/1

however I do not understand what means multiplayer or if is the data disk or so

ok perhaps I will check later such old dms file to test if there is some cpu-aga -fix


btw, this game have been not fixed for fast cpus,even the whdload version is yet linked to cpu power

the faster is the cpu the more chances of glitches or crash

Yes, exactly.


It is the best racing game ever made for Amiga so it could deserve some love.

i don't see glitches on 060 with either 50mhz or 100mhz setting, maybe an issue on accelerators which have really fast chip access.

Interesting. Could you take a video with your phone and post to youtube?

It is not like glitches. The speed is no problem. It is the gfx that at places can not keep up so it get this mirrored image. I can not explain.


This is from emulator with 040 setting I think. You see the blinking on the steering wheel and panel. This is not correct.

This is how it should look.
