Title: Help: mslug5nd & svcnd for mame
Post by: oliverkof on September 21, 2005, 09:56:25 PM
Hello,

Here below are 2 drivers for mslug5nd & svcnd. It works ok.

But when i try to use the decrypted p rom and remove:
   mslug5_px_decrypt();
   svcchaos_px_decrypt();

It doesn't work at all!!!!!!!!!!!!!!!!!! :idiot: :redface:

Anyone can help me!!!!!!!!!!!!!!!!! :eek:

Replace these:
   mslug5_px_decrypt();
   svcchaos_px_decrypt();

with this:
Code: [Select]
// hack the decrypted P data to fix bankswitch offsets
UINT8 *SRC = memory_region( REGION_CPU1 );
memcpy (src + 0x200000, src + 0x100000, 0x500000);

This should work, defintely let me know if it doesn't...

iq_132, Thank you very much!

Based on your suggestion, i arrange the drivers as below:

But it still doesn't work! :idiot:
After roms has been loaded, it just returns back to the emulator (not in the game) :idiot:

What i need to adjust further???  :idiot: :idiot: :idiot:

I thought it would be better to use the fully decrypted sets for those games

fully decrypted sets? meaning the hacked p roms?

Well it seems thats what he is wanting to do .

Anyway why does the P decrypt code need a fix ?

Hello,
Thank you for iq_132 & neo04 help!

However ... ...still have some problems!!!!!!!!!!!!!!!!! :idiot: (i post the code below based on neo04 update)

After the roms were loaded, screen returned back to emulator(not going into the games)!

I did try to use the s1 rom (instead getting data from Cx roms) to follow exactly what neo04 provided, but got the same problem(couldn't go into the games)! :idiot:

Actually i don't think there are problems about s1 roms code (from Cx roms or individual s1 rom) because the drivers are working when i use encrypted p roms!

So the problem(s) should be about the driver for p roms :confused:
could be this part:
   ROM_REGION( 0x500000, REGION_CPU1, 0 )
   ROM_LOAD16_WORD_SWAP( "268-p1d.bin", 0x000000, 0x100000, CRC(e6d297af) SHA1(5bb3f72ce26e3f46c523b955f425056eb246e855) )

see this:

so, the driver should be:

   ROM_REGION( 0x600000, REGION_CPU1, 0 )
not 0x500000, coz junk rom was loaded in the second chunk;

Post by: FerchogtX on September 25, 2005, 10:36:33 PM
Wait a sec... those ROMs are meant to have backswitch?... that things work on NeoRAGEx... at least mslug5nd has the bankswitch removed... or not?... OMG!!!!! why don't you simply use the original dumps? less problems about legitimal decryptions...
See ya!!!!!! :biggrin:

What do you mean by "original dumps"? do you mean encrypted sets? :idiot:
I've got the drivers for encrypted sets already. and i just try to add those decrypted sets! :wink:
Title: Re: Help: mslug5nd & svcnd for mame
Post by: James33 on September 25, 2005, 11:08:45 PM
Looking at your drivers you still have code that decrypts them so your not useing decrypted sets at all
Title: Re: Help: mslug5nd & svcnd for mame
Post by: oliverkof on September 25, 2005, 11:39:58 PM
I don't know much about roms & decrypted code :idiot:
Those decrypted p-roms are the only decrypted p-roms i know (for svc & mslug5) :idiot:
James33, do you know any p-roms for svc & mslug5 which do not require any decrypt code??? :idiot:
Title: Re: Help: mslug5nd & svcnd for mame
Post by: FerchogtX on September 27, 2005, 12:19:26 AM
EDIT*
I was wrong... this set still needs bankswitch... I think is better to use the encrypted roms (at least P-ROMs) instead of this, anyway needs bankswitch... if you have the PVC code It has no sense to add this semi decrypted dumps...
See ya!!!!! :biggrin:
