ok, there ya go:

Intructions: I was told on another forum to use the following settings:

Vsync: on
FS: 0

​

WOW! Just now got around to trying this ... what an improvement! Thank you so much

 

[Alucard]

Yeah - with VSYNC=on LittleJohn is the perfect NES emu for nearly any game except Castlevania III (but Akumajou Densetsu (the japanese version with superior sound, but lower difficulty) runs perfect). Thanks again, Horscht! And thanks for fMSX156, too - though it doesn't seem to make a difference (but I only tried Vampire Killer, which is already very playable with the standard version).

hmm
tis some good shit ya got here
thx man

what would be the point in there? IIRC the later versions always featured a clockspeed selection in the options menu.

About the GBA emu:

I think he meant he would like to see an overclocked version of VBA32.
I would like to see this as well, b/c it has great compatability, it just runs way too slow.
Perhaps when overclocked, a frameskip below 5 might be able to be used.

 

[Horscht]

ah, well then lemee see...... Have to get my hands onto it.

EDIT: allright, VBA32 is already overclockable, too. So no overclocked version from my side.

 

[Octavious]

woah
Ive never used VBA32
damn, its nice to see GBA on the GP!!
umm... ill think of something to OC lol
anyone know where I can find info/source of VBA32??

~Octavious

 

[Horscht]

VBA32 source is available at gp32spain

How high does it overclock to? I can't remember. If it doesn't get to 180 mhz, I'd still like to see you overclock it though, 'cause I couldn't get to 180 when I had it before but then I lost it, and now I have modded my GP32 to get to around 184 or so.....

 

[Horscht]

Octavious is trying to mess around with the sourcecode, and a "source-clocked" version would be better that just a hex edited, so i leave that emu to him. I'm one of those who overclocks emulators for a real use

 

[Goity]

would someone be able to make a 176 mhz of os9xgp? It appears that os9xgp is the only program that won't let me do 180 mhz

 

[Octavious]

Octavious is not prolly going to get anything out of it, but I would just like to look through the code and get familiar to it
The only language I know is BASIC, and a bit of C
I am taking classes for C soon, so I just want to try and get familiar to something
However, I am real busy right now, and I just made a break through on my Half Life mod, I hope to get a demo out in the next month

Is there an over clocked version of SNES9xGP? I have a BLU+ so no OpenSNES9x for me ;(

ThanX for any info, BYEEEEE!!

 

[darkplayer]

Whohoo mine gp32 went 200mhz! So i can play überfast snes roms

 

[Julius]

Any chance for a 256mhz version of opensnes? I just discovered that my nonlit GP32 happily goes to that speed in Quake and DrMD

 

[Horscht]

nope, unfortunately I don't have the parameter for speeds above 200.

Does that help? (found on this board posted by washo):

in gpsnes9x.cpp:
switch (gp32_clockfreq)
{
case 133:
gp32_clockfreq=144;
break;
case 144:
gp32_clockfreq=156;
break;
case 156:
gp32_clockfreq=166;
break;
case 166:
gp32_clockfreq=180;
break;
case 180:
gp32_clockfreq=200;
break;
case 200:
gp32_clockfreq=220;
break;
case 220:
gp32_clockfreq=240;
break;
case 240:
gp32_clockfreq=256;
break;
case 256:
gp32_clockfreq=133;
break;


}

in gp32_func.cpp:

}

no, unfortunaly I have no clue about compiling or coding at all (all I know is that what you posted is code), what I do is Hex-edit already compiled fxe's/gxb's. So I can't use the code you posted to hex edit the fxes.

​

mirko's gp clock tester has all frequencies from 133 to 256 with a step of 4 MHz, maybe you could have a look at it to find the hex values ?
