Lotus Trilogy

10 January 2005, 15:42

Hi Everyone;
I recently downloaded the "Lotus Trilogy" iso from Back2Roots.org but unfortunately when you try to play Lotus Turbo Challenge 3 it comes up with a "Fatal Checksum Error". I suspect that it is a faulty iso as I burnt it to disk and tried it on both a real Amiga CD32 and the WinUAE emulator. I even ran the iso through Daemon Tools and it does the same thing. The thing with this iso is that it has been tampered with: i.e the audio tracks have been converted to mp3 in order to decrease the size of the download.

I was hoping that someone might be able to provide me with a proper FULL iso image from the original disc. If anyone does havre one could they please reply to this post.

Thanx Heaps
Moff

I have an original copy of the game and I get the same message when using WinUAE. But it works on my real CD32...

Fred the Fop · 10 January 2005, 17:28

Have you tried converting the mp3s into wavs?Can you rip this image into iso/mp3?

Amiga1992 · 10 January 2005, 20:31

No duplicate posting please.

Yes I did convert all the mp3's to waves and I adjusted the cue file accordingly, and that part of it worked fine. Its just that confounded Fatal Error message that bothers me.

this thread is 2 years old, ithink it's time to ask:
Is there somone who arrived to make this cd32 title work perfectly in winuae.Did you arrive to launch lotus 3 with cdda ?

Retro-Nerd · 13 April 2007, 17:52

Lotus III still crashes with a "Fatal Checksum Error". But i don't know if the Tosec ISO+WAV dump or WinUAE causes the trouble.

What about setting, EXACT CPU and CYCLE Blitter ON, in WinUAE. I had this problem with Microcosm (Original), after setting this option ON, it ran flawlessly.

turrican3 · 14 April 2007, 01:21

For microcosm ihad this problem too, but with lotus trilogy it's more difficult i tried with pratically all settings but i don't try for a long time now.
i tried again afternoon with a new version no more results but if someone can do it i just want to know, but i doubt.
But without asking I have no chance to know.
very hard problem

nobody give a clue i think, however i searched everywhere on the net.

Thank for giving a help.
If there is someone how can confirm that there the same problem with the original

turrican3 · 19 May 2007, 18:04

toni,
Do you know why lotus 3 in the lotus trilogy compil crash when the game ask for disk 2?
Nobody never arrived to pass this problem with original or copy.
look at the screenshots but i'm sure you know the problem,it's a so old problem.

Is there somebody else who has the original and can confirm please

I have been debugging this today.. For some reason wrong sector is read few times (which results in wrong checksum) when reading "second disk"

First "disk" is always correct.

One possibility is loader timing bug, loader sends bogus CD commands very regularly when JIT is enabled and only few without JIT.

(this game uses custom loader, instead of standard extended rom driver)

turrican3 · 10 July 2007, 16:48

Does it mean that you can do something for it to work.
Or does it mean

.
Thank you for your great work with the beta 9

turrican3 · 13 July 2007, 20:16

dear toni,
do you think you could make it work ?

Toni Wilen · 14 July 2007, 14:25

I tried but I lost interest quickly.. CD32's drive controller is so weird, it has nothing in common with CDTV or SCSI which makes understanding it very difficult. (it has weird read-write 16-bit "sector bit mask" register which is really confusing feature)

Also (IMHO of course) working CD32 Lotus 3 is not worth the trouble. Lotus 3 was huge disappoinment ("track editor" is useless, serial link disappeared, slower than Lotus 2 etc..)

Find another non-working game that needs same fix and I'll think about it again

turrican3 · 14 July 2007, 14:44

thnak you,
i don't agrre with you for lotus 3, for me it's the best and it use great cdda in this version.

Indeed, I like the third one as well but then I played that before the other two so that may have something to do with it.

turrican3 · 14 July 2007, 19:49

this is the last game i'm waiting, all the others i like work great, and just the video(i don't remember the name of the format) intro of some cd32 games (ex: james pond zool), that's all for my use winuae is near perfection.

ps: sorry for my bad english

turrican3 · 08 September 2007, 21:16

That's it jotd patch the cd32 version and it work now for winuae

A great thank to jotd

Enjoy this one.

jotd

PS: you must had the musics in wav format and after burn it or mount it with daemon tools.

I remember getting this error message when playing with caches enabled on my A4000. Disabling them made the game run. Also never had problems running LotusTrilogy (including Lotus3) in WinUAE. I have to add though that it's just a rip without audio tracks.
