Homebrew Gxgeo Usb mod

[bm123456]

Hello I'm a big fan of this emulator and everywhere i read , the author hasn't released his source but he states that he would release it upon request .. if so i think every one would love to not be restricted to a sd ..I know this site has some great coders so i thought maybe someone would like the challenge i know everyone would be happy , i know i would thanks

 

[Slimmmmmm]

Well ... get the source, upload it somewhere and post a link.

You can't expect someone to do ALL the work.

Also I'm not familiar with that emu, what else in your opinion needs chaged ?

 

[Wiimpathy]

The source code is here : gxgeo
I quickly try to add usb but didn't manage to make it work for a mysterious reason.

It's really sad since there's no update for months and it lacks a Big feature : Big roms support.
I really hope the author don't let it down cause on GP2X you can launch big games.

However you can use SDHC card for larger storage.

thanks Wiiimpathy , .. i posted on here to maybe spark an interest to a friend of the author to point someone in the right direction ,, its really a great little emulator just hasn't seen an update in a while ..

You can try this Gxgeo-usb.

When the emulator starts, press Wiimote 1 for sd or 2 for usb. It works on my Wii (although usb is a little slow
since it's usb 1), not sure if it will work for everybody.

Super Coooooool!, I'll tweet it on my twitter
thanks a lot!!!!

Great maybe someone can help mod this to 2.0 , this is Great Wiimpathy .. at this rate we might have to start looking or making a great forwarder that points to usb .. I'll give it a try when i get home and post my results

You have to use IOS58 or CIOS202

IOS58 : ( add it in the include ) #include

Spoiler: In the Main.c before int main

/****************************************************************************
* IOS Check
***************************************************************************/
#ifdef HW_RVL
bool SupportedIOS(u32 ios)
{
if(ios == 58 || ios == 61)
return true;

return false;
}

bool SaneIOS(u32 ios)
{
bool res = false;
u32 num_titles=0;
u32 tmd_size;

if(ios > 200)
return false;

if (ES_GetNumTitles(&num_titles) < 0)
return false;

if(num_titles < 1)
return false;

u64 *titles = (u64 *)memalign(32, num_titles * sizeof(u64) + 32);

if(!titles)
return false;

if (ES_GetTitles(titles, num_titles) < 0)
{
free(titles);
return false;
}

u32 *tmdbuffer = (u32 *)memalign(32, MAX_SIGNED_TMD_SIZE);

if(!tmdbuffer)
{
free(titles);
return false;
}

for(u32 n=0; n < num_titles; n++)
{
if((titles[n] & 0xFFFFFFFF) != ios)
continue;

if (ES_GetStoredTMDSize(titles[n], &tmd_size) < 0)
break;

if (tmd_size > 4096)
break;

if (ES_GetStoredTMD(titles[n], (signed_blob *)tmdbuffer, tmd_size) < 0)
break;

if (tmdbuffer[1] || tmdbuffer[2])
{
res = true;
break;
}
}
free(tmdbuffer);
free(titles);
return res;
}
#endif

Spoiler: In the main c after int main

#ifdef HW_RVL
L2Enhance();

u32 ios = IOS_GetVersion();

if(!SupportedIOS(ios))
{
s32 preferred = IOS_GetPreferredVersion();

if(SupportedIOS(preferred))
IOS_ReloadIOS(preferred);
}
#endif

Code from snes9xgx

It should run at USB2 speed if compile successful

Thanks matguitarist, I already saw this code but couldn't test cause I didn't have
this damn IOS58 (was using 202 instead).

I had problems compiling with latest devkit related to file operations etc... so it's
compiled with r22.

Anyway, it should work at last with IOS58.
Here it is : GxGeo-Usb2

i can confirm this works great with my western digital 1TB, worked first time, thanks again, Wiimpathy , I' ll test the new usb -2 mod tonight and report back

also , i tried troy zombie forwarders for these and they don't work ,, maybe we can look around for a forwarder or i'll start to make one myself .thanks again

Gxgeo usb2.0 mod works great ,,easy to test your roms on ,, I used troy zombie forwarder and inject your dol worked great on my western digital 1TB ,,

Thanks for this mod it really need it

 

[bm123456]

Anyone interested in not getting the memory issues with this great emulator , download Dumpgfx , it runs in windows and it will create a .gfx file that needs to be placed in the roms folder with your current roms ,
or seach for a complete set of roms with them already there , just use google i won't give any links for this but yes you can find them .


So that being said we need to look into tweaking the way this emulator handles the .gfx file like with the GP2X and Wiz ..in which this emulator was ported from ,

 

[aReFeS]

Works perfectly.

Saves a lot of room on my SD.

Thanks a lot!

 

[bm123456]

Glad to hear ,, aReFeS , i love how fast this thing loads ,, if you need a forwarder u can read my post from above the one from troy zombie works great ..i love it

 

[PolloDiablo]

I will try this later! thanks a lot!

 

[Bladeforce]

[bm123456]

[PolloDiablo]
