Prince Of Persia Floppy Disk Copy Protection can't be past #59

Closed BenoitAdam94 closed 1 year ago

BenoitAdam94 commented 1 year ago

So, I'm able to launch Prince Of Persia 1 on Tsugaru FMTown Emulator (24/09/2022) but I can't past the copy protection.

I have the floppy disk in *.bin format

Mount FD0 before launching the game => Doesn't work Launch VM => FS0 => Select FD Image => Choose & Mount the floppy => Doesn't change a thing, still got the error message

Your screenshot is saying "Insert user disk in drive 0 and press enter." Is it really a copy-protection? Or is it waiting for a user disk?

Anyway, .BIN format does not replicate copy protection. All known copy protections to date (known to me) for TOWNS can be replicated by .D77 format. Please try to make .D77 format from real disk and try again. I suppose you understand it, but converting .BIN to .D77 doesn't help because .BIN already lost copy-protection information.

I'm going to talk about my copy-protection research in Demosplash in two weeks (https://www.demosplash.org/) Please join us if you are interested.

I think it's waiting for a user disk, but for me it seems like it's a copy-protection.

Same problem on Prince Of Persia 2 :

I will check demosplash, do they upload broadcast on Youtube ?

4D Sports Driving does ask for User Disk but it can be skipped.

Ok I'm getting it :

I needed to create a new floppy disk trough "File" > "New" > 1232Kb Floppy Disk Image

Hell, not very simple to handle this emulator on first start... I'll write a guide and make a video on it probably because it's really hard for New Comers

One last question, can we change the defaut save folder for Profile/Floppy/savestates ?

"C:\Users\Benoit\Documents\Tsugaru_TOWNS\" isn't convenient for me

(by the way I think Would be great to be able to choose 3 differents paths)
