Lotus2 extremized speed test

[kremiso]

another funny test, made combining the Goonies infinite turbo cheat, the NOMAD AGA fixes, and 60Hz

directly into the second stage, the nocturne one (twilight code)

i think this is the max speed this engine can reach

default A1200 to reload, but should work on other 680x0 cpu's too, with 2MB Chip

>>> ADF test uploaded to TheZone <<<

not to play the game, just to test the engine extremized, btw you can play also the rest of the game inserting the fixed for AGA NOMAD adf after the boot

[DanyPPC]

Good test, so on A1200 graphics can be improved mantaining the original speed.

[jotd]

game could be made even faster on AGA by enabling FMODE=3 (fast bitplane fetch) and leave more time for the blitting operations.

But it's not that simple, specially without the source. We did that with Ross on Supercars 2 (AGA) but a lot of sizes & memory buffers needed to be aligned for it to work.

[kremiso]

it does seems an F-zero chapter on Amiga

it can be useful to instantly check the slight speed difference between 68000 and 68020 in that stage

Slightly off topic but did anyone try and modify "Lotus Esprit Turbo Challenge" for full screen play in single player? also with the ability to change music track between races?

Most likely beyond the scope of a WHDLoad patch but I remember people saying a long time ago they had the source code for the first game.

[jotd]

I have the source code.

this is like Amiga version of SPEED with the accelerator stuck on ON i kept bouncing left and right against billboards too funny

i always loved getting into this level and see how fast i could be is this the original game engine or have you modified it? can we get the whole game with this performance?

That would be something special

yes the original engine, i have just combined the infinite turbo mode with the AGA fixes, to make it work on A1200; and pushed at 60Hz

on standard game, the turbo can be collected for an extra bit of speed just in the last stage iirc

the infinite turbo mode can be tried on OCS in the Goonies adf crack

yes an AGA boot version starting from the begin can also be made

Oh nice, How challenging do you think it would be to create a full screen version with track selection between races? Also is there any unused serial link code in the source? Lotus Esprit Turbo Challenge with 4 players would be awesome.

I was always more of a fan of the first game vs 2 and 3 but I do like the additional features in the sequels. Serial Link from Lotus 2 and RECS from Lotus 3.

[kremiso]

doing further tries on the Goonies crack
a friend is testing on a real A1200

seems that playing the game with that turbo mode doesnt trigger the freeze crash on AGA real hardware

so i think the turbo mode can be tried as it is also on AGA systems (i mean to play the entire game)

a little shame no source code for this, this engine is faster than the Lotus3 one, it would be cool also a somewhat hack of that

EDIT also interesting the difference between 68000 and 68020 in the second stage, as there isnt the road going backward effect in the tunnels using the latter config

Apparently this is from the new Atari STE port.

[kremiso]

now thats a sweet sky gradient

didnt know of this STE upgrade

[Retro1234]

I know no-one will believe me but once something went wrong with the WHDload version for me and it was so fast it was unplayable. I normally play it in NTSC mode but this was something else, heigh-ho.

I tried lotus_ste_v1_0.st and the screen doesnt look like that.

Normal split screen..

Oh I see it in the readme

Possible forthcoming objectives for this project are as follows:

Fullscreen mode for player 1;
New tracks, or modification to existing tracks;
Modified trackside objects, or additional zoom levels for trackside objects.


* Seeing the project was released 3 years ago I doubt its still in production?

Well at least we can salivate at what could have been.

[Adropac2]

oh man full screen would indeed be a glorious thing to behold on the Amiga

We follow each other on Twitter, his last posts STE wise were last year upgrading Lotus 2 for the STE, i have now asked him regarding the single screen mode.

Nice one

[Amigajay]

He came back saying he hasn’t had the time since last to get back on the STe projects, so they aren’t closed as such.

As for Lotus 1, he says it was unlikely he could get it running at a decent speed to use the full screen mode without taking a big framerate drop, so i think he didn’t continue with that once he tested it.
