Floppy Disk Stream Image Repository

Does the SCP boot in Steem etc? What does an image of the newly written disk look like?

Does the SCP boot in Steem etc? What does an image of the newly written disk look like?

Hi, yes it boots on Steem. I am trying to run/test the SCP image on real hardware because the game will crash if the main demonstration loop is left to run past the hi-score display on emulator. On the 3rd or 4th pass of the demo/title screen loop, the high-score will be displayed with garbage as you can see here:

After that, the US Gold logo is displayed again then the little bomb bounces on the screen and there is a crash which resets the machine. I'm trying to determine what causes this or if the original game was bugged. I have tried with Hatari 2.5.0-devel, Steem 3.8.0 and Steem 4.1.2 R1. I've also used the Elite and Replicants cracks from the GameDVD and both also crash the same way. I tried both of the stream repository releases "mega_twins_us_gold [SCP-IPF].7z" and "RavingMad_MegaTwins_U.S.Gold_Disk1-2Of2_AtariST_Dump[GW](mikerochip).7z". Also on emulator with 512kb, 1mb and 4mb configuations, both STE and STFM.

So, the only thing I haven't tried is running from real hardware with flux image written to disk as I don't have the original disk to try.

Has anyone else encountered this crash or know what causes it?

[Mikerochip]

How are you writing them to disk, then? What's the error?

[TheNameOfTheGame]

I was trying to write it to disk with my SCP device. I have used it in the past to make physical disks and it worked fine, but that has been a few years so I may have forgotten something. When I load the flux image "MegaTwins_a.scp" into the Disk Archiver program it looks like this:

megatwins_scp.png

After pressing the "Make Disk" button it writes the disk and looks like this:

megatwins_scpdone.png

But trying boot the resulting disk on my STE results in some light noise with the read head for about 30 seconds then it drops to the desktop.

[Mikerochip]

Ah.

I've only used a greaseweazle to write the disk images back.

If you image that blank floppy again, does it work in an emulator? Or, what does the disk look like in aufit?

Just in case the software is doing something funny, make sure the disk type bit is set, in the .scp file?
https://github.com/M1kerochip/LaunchGre ... skType.exe

Run the exe, pick the .scp file, and set the disk to be Atari, and ST double sided.

I can't think of any other reason why it wouldn't work

Hi TheNameOfTheGame I have tried all the images on Steem & Hatari and had the same results as you have. I was looking at your screenshots of your SCP software, i haven't got a SCP myself, just a Greaseweazle, but i see that you said you haven't used it in a while and from the pics you uploaded, your software version is 1.95 and i believe it's now on V2.50, also there may have been a firmware update since you last used it. Maybe worth asking in the SCP section, if an update doesn't help. Hope you get it sorted, cheers Dave

damn.....

At least, the Greasleweasle allows to write IPF And Mega Twins in IPF works correctly

EDIT : I'd simply say that the game is just faulty. If done correctly, it should not have a crash and gfx corruption.

At least, the Greasleweasle allows to write IPF And Mega Twins in IPF works correctly

Hi dlfrsilver, i have tried the IPF version on the latest hatari - 2.4.1 and it does the exact same, with the graphic corruption and on the 4th time round it resets. Need to try dumping it back and testing it on my ST and see what happens ... While your there Maupiti Island UK language, has it ever been dumped ?

Have already tried IPF in Hatari and it still has the corruption and crash.

Thanks for the suggestion. Updated to v2.50 of the software and firmware 1.3 but still won't reproduce the flux image to physical disk. Very strange.

[Mikerochip]

Do all the other versions. Stx. Cracked etc, do the same? I'll try my scp on the gotek tomorrow.

[TheNameOfTheGame]

Yes, I've tried the STX, IPF and SCP versions from the repository as well as both the Elite and Replicants cracked versions from Marcer's GameDVD. All do the same thing under Steem/Hatari and crash shortly after the corrupted hi-score screen.

As I mentioned previously, the SCP does run in Steem although it crashes at the same place as the other versions.

I am having problems writing the flux image to physical disk to test on real hardware. Not sure what is happening there. Thanks for testing on real hardware. Looking forward to the results.

[Mikerochip]

It it only crashing if you leave the intro playing?
Can the actual game start ok?

Correct. Crashing on the intro loop.

Game starts and plays the first level but I haven't tested the entire game.

[Mikerochip]

Sounds like a good time to get a gotek...

[TheNameOfTheGame]

So your handle is on the Raving Mad compilation dump in the repository. Did you dump the physical disk? Can you test the original disk on hardware?

[Mikerochip]

I can do both gotek and floppy. Yep, I dumped the raving mad compilation.
Itll probably be tomorrow evening.

[TheNameOfTheGame]

Super..sounds good! Thanks.

In fact, i have a second dump of Megatwins from my own Raving mad compilation. the problem comes from the original (or it is an emulator problem).

Because per se, I got no data errors when encoding in IPF.....

[dlfrsilver]

@Dave Harrison : Maupiti Islands Uk is dumped, here : https://we.tl/t-mZ5sVWTV3h

[dlfrsilver]

here are the files for Mega Twins for Gotek HFEv3 : https://we.tl/t-8dBpFYQSzi

[dlfrsilver]

It seems that MegaTwins has either a programming error or an emulator error. The graphic error we have is a graphical error (seems to be a bug not fixed before mastering) forgotten.....

The score page has 2 pages, both are corrupted, looks like the programmer ask the program to print tiles number out of range.

Any programmer can help on this ?

EDIT : In fact, the scores are graphically corrupted. It's like that on all the versions : retail and compilation.

Cheers for that, i checked the retail and compilation versions also and like you said they both do the same. It had to be a programming glitch, as even the cracked versions were doing the same, just too much of a coincidence and i knew for certain the ipf's were going to be spot on
