Speedy GBA Emulation - Most notably morphgear

01-14-05, 11:07 PM

I've seen this question asked many times before, but all the links that I'm told to follow (like http://www.morphgear.com/forum/forum...posts=17#M7027) lead me nowhere.

So.. I'll ask again. I currently emulate GBA games via morphgear, but everything (other than RPG's and other slow moving games) is very slow and not very playable. However, I have heard mention that there are ways to speed up GBA emulation. Does this require overclocking.. because I thought 600+ MHZ was fast enough!:rolling:

For the record, I'm using an X50v with the power set to 624 MHZ.

Here's a thread I made explaining all, If you need any more help, Post on the Morphgear Forums or email me:

forkyfork, unfortunately, GBA emulation is slow. Da1writer's post helps in speeding up GBA a little, but even he admits he only gets 17 - 28 FPS in FS1 without sound (which is from 57-93% actual gamespeed skipping every other frame). I also don't think GBA emulation will improve that much since it would require some time-consuming reverse engineering to improve the gamespeed substancially and the fact is no one seems to be that interested in the GBA (as opposed to say the PS1, SNES or other consoles, albeit being much older) to want to waste their time doing so.

I figured *sigh*. At least GBC games are fast.

And I was very surprised when I played an SNES game on my Axim with SNES Bleeding Edge. Wow!

Most of my games run at about full speed so I'm not sure where people have troubles... I get Harvest Moon running at full speed :)

What is the sound quality like when you run gba games at full speed?

For most developers the interest in gba emulation is low just due to the piracy factor...at least with older systems you cant buy them anymore and there is at least a bit of a preservation factor involved.

I don't know. Take a look at playstation emulation. And IIRC, GBA emulation is still pretty slow on PCs aswell.
