The result of what is basically a morning's work:

http://www.squidgey.plus.com/spot.zip

Yes, it's slow, but at the moment it's all written in C with no optimisation whatsoever

(At least let it run to the menu screen where it gets a lot faster).

No, there's no joystick control, or anything else for that matter.

And no, DaveC, there's no sound

This was the real "Mystery Project", the car thing was just a side project. I've just not had the time to code

So... What is it?

Try it and find out

Hey this isn't the version of the original Spot reversi/othello style board game is it? The Spot that went on to become Cool Spot?

Ah. Now that is very, very good!
wow!
You really should try it to find out

excellent!

i dont think anyone saw that one coming!

I've not seen the 'source' for this, but is it what I think it is?
if so then I'm very glad I voted for 'mystery project'

A GP32 emu!?

I thought this might be what it was.

Actually, that was the red spot on the 7up can.

Mm, smells like backwards compatability.

Dude, cool!

I approve of this.

Yeah! Nice one

Not exactly sure what it is, got to the menu.

Looks intriguing though

Whippersnapper...

This makes me feel all nostalgic...

Care to inform this whippersnapper?

It's the GP32 BLU firmware running on GP2X. This has made my day.

Does it emulate BLU or BLU+

Ahh ok

Very cool stuff indeed!

Sweet, especially for us old GP32 owners.

But after givin it a little thought... are there really any good programs available for the GP32 that arn't for the GP2X? Right now I can't think of any

just popped it onto the sd card, cant wait to try it, Great Job!!

and wow, i havent seen this in a while! thanks alot Squidge!



also

whippersnapper - noun - whippersnapper, jackanapes, lightweight - someone who is unimportant but cheeky and presumptuous

holy mother of hell.

I would love to play Blue Angelo on my GP2X...

Whee!!! Now maybe I can get a chance to experience a little gp32-ness, too :-)

I do say, a worthy mystery project :-)

and Mafi Sushi Panic!!

(there were tons of great 32 homebrew still not on the 2x, and if this could run them, i think i might just wet myself)

I suppose it could someday. The GP32 didnt have any dedicated hardware I think...

Nice... I'm glad people vited forthe mystery project now! I can feel the GP32ness on my 2X! Thanks Squidge!

Yup I wonder if this will ever be fullspeed

Hope so, then maybe we can finally have a good PC-engine and NES emu using GPEngine and LittlejohnGP32

Do not lose hope in the Vobbo Besides, GP32Engine doesn't have save states, but it is amazing.

great PoC Squidge!

I was never lucky enough to own a , so this'll be a very interesting project to watch develop!

I've been speaking to Squidge about this. This is my favorite project going right now! Waiting for Squidge to come on to talk about some virtualisation techniques. I think Squidge is fully capable of this project's success and he has my full support. I'm amazed he was able to get this up and running so quickly. Fantastic work Squidge. Don't forget the MSN.

Zodttd and Squidge communicating

Squidge, DJ Willis, unai, and skeezix are some of my favorite homebrew developers.

I too never had a GP32, and having it on the GP2X will be especially useful in the future in terms of backwards compatibility. I'm super excited over this project. It may open up a new avenue for some of my projects as well.

For those who are unaware, this is a major development. The fact a release of Spot came so quickly gives me great hope. Thank you Squidge.

Incredible O_o

Squidge is amazing, especially if re-enforced by Zodttd. Woo. GP32 and GBA, my life is complete

Hmm, so how does it work?
I gather from what Zodttd said, that it is not an interpretor nor a dynarec, but something else?

Heh, the GP32 uses an ARM processor and NO dedicated hardware... should be possible using DynaRec

BTW: Slubman Firmware and Mr. Spiv's Multifirmware doesn't run yet

Well, the GP32 is like the GP2x in many respects. Both use an ARM9. GP32 doesnt have a hardware scaler etc or video decoder to emulate.

this mean tobi drummer may eventuallyl work?

Lol. Indeed. I only tried that once...ever...

Damn. I could not believe my eyes when I saw that sweet little logo fade in from the white background :-) Thank you Squidgey!

Think of virtualisation like this:
Two systems have the same CPU's using the same instruction sets.
They may have completely different hardware for graphics acceleration and controls, etc...
Virtualisation let's you run one systems code natively on another system and hooks into the calls to certain hardware and emulates only that portion.
You can see why I'm interested in this. Expect some news on my front soon.

Thanks Squidge
I imagine myself geting a GP3X after 3 years, running a GP2X emulator on it, running a GP32 emulator above the GP2X emulator, and running LJ NES emulator over all this

lol

This is virtualization? I thought it was just an interpreter.

Its not metioned whether its currently using an interpreter.

Hey, I'm coming from ZodTTD's thread, so correct me if I'm wrong, but:

interpretation<dynamic recompilation<virtualization

Guessing here, but for virtualization, you'd have to know and understand the entire instruction set of the target CPU in order to get it running on the host CPU (which would mean pure assembly)? Is that what makes it so complicated? It is more complicated than a dynarec right?

Anyway, amazing stuff Squidge!! Looking forward to playing some GP32 apps!

Why's it called spot?
