M1 Decrypted !!
« on: September 18, 2008, 04:56:42 PM »
Andreas (  http://andreasnaive.blogspot.com/ ) has succesfully decrypted the neogeo M1 roms. He hasn't updated his site yet, but this will remove the need for the (bootleg) m1_decrypted.bin files for all games newer than kof2000 in MAME.

I'm currenly porting his code over, but, I thought this was worth mentioning as it's taken a long, long time for anybody to figure out, and he managed it in under a week :-) Very good news.

I´ve been waiting this moment for years.... finally we can have proper roms.

I hope nebula and winkawaks will be updated even if i dont use them (i use mame or fba), it´s a pity those emus are very outdated nowadays.

Same...I hope.

It's easy:

If nebula = opensource
then nebula => safe
else nebula => dead

If (nebula == opensource)
{
   nebula = safe;
   still_use_fba = true;
} else {
   nebula = dead;
   switch_to_fba = true;
}
:biggrin:

I have to make some modifications too IQ xD...(the 'If' was 'if' lowercase, and renamed variables to follow the coding standards a bit LOL)

 :biggrin:  :p

Quote

#define OPEN_SOURCE_APP      TRUE
#define APP_STATUS_SAFE      1
#define APP_STATUS_DEAD      0

int CheckNebulaGrave(HANDLE hNebula)
{
   bool bNebulaType = GetApplicationType(hNebula);

   if (bNebulaType == OPEN_SOURCE_APP)
   {
      g_bNebulaStatus = APP_STATUS_SAFE;

      if(1 + 1 == 2) {
         g_bStillUseFBA = true;
      }

      return g_bStillUseFBA;

   } else {

      g_bNebulaStatus = APP_STATUS_DEAD;
      g_bKeepUsingFBA = true;

      return g_bKeepUsingFBA;
   }

   return -1;
}

SeeYaa!

LOL!, That looks acceptable  :cool: xD

btw, Andy is not updating his blog!  :mad: (*scream*), he seems to be writing words from the dictionary, my original language is Spanish but he uses words in his blog from another world xDD LOL, to find them I have to look at the RAE (Real Academia Espanola) web page  :p

SeeYaa!
