EPIC working on WinUAE-CDTV, but not on a real CDTV

mk1 · 23 March 2009, 19:11

Hi,

bought a copy of EPIC to feed my space opera hunger. Tried running in on my CDTV but after a few seconds of loading (the logo shows up) the game crashes badly flipping the whole machine over booting the clock and making the screen jump and change colour. Tried removing all the periphals except for the disk drive, but it had no effect.

Tested the disks on my A1200 and the work fine. I then downloaded a copy (cracked naturally) of the game to test in on WinUAE and it works well.

Any ideas what might be wrong and how accurate is the WinUAE emulation compared to the real thing anyway? Could it be that there's not enough memory for the game with the disk and cd drives taking their share of the 1mb chip ram? How come it then works on WinUAE?

have you tried running the cdtv in a500 mode? open jp15 for this (it's on the mainboard...)

What is this supposed to prove if you tested different game "versions"?

mk1 · 23 March 2009, 19:27

No go, but thanks for the tip. I didn't know such "option" even existed

Well, it'll give a hint at least. I wouldn't think cracking a game fixes loading problems, but I guess you never know.

Anyhow, there's not an uncracked version around and no way to transfer those disks to a PC so that would be the only option.

EDIT: Could it be that it doesn't like the cdtv disk drive? I don't have a spare one to test the game on but at least the loading sounds are rather different from the A1200 disk drive.

OK, it's not the disk drive as it loads just fine when hooked to a CD32.

Cracked non-dos games usually always have different loader.

I guess the question is: does the cracked version work on CDTV?

Epic didn't have on disk copy protection, so there would have been little need to change the loader on this one.

Indeed, that's true.

At least the cracked disk, if it actually was cracked, didn't have any intros or anything there. Unfortunately I don't have the means to test the crack on the real system.
