CUBO CD32 Games.. - Page 6

nikolaos1960 · 07 July 2017, 15:14

I found a solution in MAME!
It works fine,in version 0.153 ,and maybe earlier!
Of course i will wait for WINUAE because graphics are much better!

Toni Wilen · 07 July 2017, 19:37

I am sure I mentioned this already. There is nothing wrong with WinUAE. It is game protection and MAME just patches (cracks) the image on the fly. I don't do game specific hacks.

Correct method is to someone dump the game's NVRAM data from Cubo. I am 99.9% sure the protection is simply checking that NVRAM has expected data.

nikolaos1960 · 07 July 2017, 20:13

Thanks Toni!
Unfortunately i am not familiar with such programming Knowledge to do it my self,so i have to wait for someone else!
The good point is ,that i have it working,and i can wait less anxious!
My compliments for your great work in Amiga,i always admire people who can do great programming,and help people,without any prophet!

Does MAME modify the NVRAM too? Because if it doesn't wouldn't the NVRAM data from MAME work for this?

Exactly what I was thinking after Toni's post

...I guess MAME patches NVRAM data the on the fly.

Toni Wilen · 09 July 2017, 07:46

No, it patches (cracks) the game executable, disabling the protection check.

brolly · 10 July 2017, 09:18

And will that affect the NVRAM data at all? I would think no and if so maybe you could make use of the NVRAM generated in MAME?

earok · 10 July 2017, 11:54

I'm pretty sure what Toni is saying is that there is NO NVRAM generated in MAME, rather MAME cracks the game so it doesn't need to access NVRAM.

If someone happens to have an original Cubo machine I might be able to give a hand with getting the NVRAM data out... at the very least data stored in NVRAM is small enough to be converted to BASE64 and printed on a screen, so I've got a utility sitting around somewhere for just that purpose

rygar · 10 July 2017, 16:54

I don't think that MAME cracked game. If protection is NVRAM ralated they could dump it easly. It's opensource code so it could be checked :P

brolly · 10 July 2017, 23:38

MAME does save NVRAM, I uploaded the NVRAM generated for Candy Puzzle to the zone in case Toni wants to have a look and see if it's of any use.

Interesting.. you can indeed mount that NVRAM file with WinUAE.

So it wouldn't be that hard to rip the save, put it on a disc, put the save back on the real NVRAM of a CD32 (especially as the save takes up only 1 block).

Are there NVRAM files generated for the remainder of the CUBO games?
(particularly Harem Puzzle)

brolly · 11 July 2017, 04:45

I'd guess so but didn't test it just did a quick check with Candy Puzzle to see if it got generated or not.
If the NVRAM ends up being of any use I can check the others.

Gzegzolka · 11 July 2017, 06:09

I wonder how You can solve setting nudity level option. As far as I remember in mame there was an option for service menu with those stuff.

brolly · 11 July 2017, 10:00

That should get saved to the NVRAM.

From memory <F2> is the service menu key.

Edit: yes it is:

Hi guys, some hints (like Toni

) to patch Harem Challenge.

If you have a right CD32 ISO looks with hex editor to hexadecimal offset "12513e50": if you find 000197FE303C0001 you are on track.
Change the last byte (01) with 00..
Alternately you can change the byte in executable (aree.exe): the right hex offset is 10657, change 01->00.

Bye

ross

DamienD · 25 August 2017, 23:04

Wow, that was quick

...not home now so cannot try this until tomorrow afternoon. Will post / update the thread then

jotd · 26 August 2017, 11:00

do you think WHDLoad slaves would be possible? I could take on that task.

ross · 26 August 2017, 14:37

Sure.
I've made some little change, ripped files and voilà: game started from HD

Salut!
ross

DamienD · 26 August 2017, 15:37

Cool, where can one find the files? Would be good to install to plain hard drive for me

Did you do the same with Candy Puzzle?
