I would like to do on my spare time a pseudo 3d engine,are there some good tutorials?

oh.. u beat me ....... Stunt car racer. :)

Super Hang-On :) Great on the old ST. Don't shoot me!

Bam! ;)

Lotus 2

Vroom was good to although i dont think it qualifies as an outrun style game

Have a look at http://www.extentofthejam.com/pseudo/ , it covers the general principles involved and also has specific info about the tricks used in Lotus, Test Drive 2, Road Rash, etc.

You got me! :)

So I take it the Amiga version was the best conversion?... Thank God for MAME! :D

The MegaDrive and later the Sega Saturn version were better ;) The article says that the Amiga version is better than the CPC and Speccy versions... no comment there :D

Sega Saturn and Dreamcast Ports (Yu Suzuki Game Gear Works Vol.1) . All other ports looks/plays dated. And of course the great fan made game based on the arcade version, it runs in full 60FPS.

Wow this gets even better! I presume it requires the arcade rom image?

Yep, you need the Arcade romset.

I can give you one of the worst: Outrun itself.

Outrun on the Amiga was a huge disappointment. No help from the copper for creating the road. No blitter use. Nearly everything is done in software. It's a direct port from the ST.

Compare with Lotus 2, which uses the copper to stripe the road and blitter to help build the display. They even use blitter interrupts to allow the blitter to run concurrently with the CPU. (While tinkering with the WinUAE debugger, I turned on blitter-nasty, which slowed things down a bit. Allowing blits to run concurrently with the CPU definitely sped things up.)

They still have a 16 color display during game play to make porting the graphics between the ST and Amiga easier, but the frame rate is great. I think for some of the static screens they used EHB and 32 color screens.

If that's the case is there a project to improve the Amiga version of outrun?

No way! If you polish a turd, it will still be a turd...

@Lesta_smsc :it would means to use the arcade code and adapt it to amiga. the amiga code port is just pure garbage.

the amiga outrun port is at best 10 fps, 15 maybe.

Putting a breakpoint at the beginning of the VBlank int handler, I count 7 to 8 VBlank ints per frame while it runs in demo mode.

10 fps is generous!

I think the worst I saw with Lotus 2 single player was 12 fps, but often times it runs at 25 fps!

Just tried this! Blimey, it does look a lot better! Much smoother on the gameplay, I suppose the increased FPS makes a hell of a difference! :D

In fact, I would go ahead to claim that the c64 port is in fact superior to the amiga version. At least the c64 game runs with a decent framerate and the music is actually very good too.
