However it ignores HDD completely.

I need to debug it, but first need to readd debug code that was removed in previous versions.

I have gained 3 - 4 FPS,

. Most people will still moan, but I can now play Bubble Bobble with FS = 1,

. So Im happy.

I think my main problem is, I have left it for so long, that I cant remember some of the stuff I learnt. Some code I cant even workout how I ever thought it up, its that complex, lol.

I was also looking at the Media Audio implementation. It looks as though in the test build, they were running audio on both main cpu and the me cpu. Which I think would defeat the object and thats why I never looked at it.
Maybe will look at it again.

Is Media Audio related to the Media Engine somehow?

One thing I recently read about ME is that apparently any emulators which use it can't be signed for some reason, hence why people have had to go back a few versions to get a signed Snes9xTYL up and running.

Hey FOL,

this was our chat on dcemu a year ago

Thank you for your hard work""

Dont worry, Im always trying to improve it.

Im hoping that someone can help with the ASM core, then we should see full speed hopefully.

Lost me with this.

To be honest, I have been so busy over the last 2 years, aint had much chance to work on it. Plus Im still not getting coding help.
Ive only just got back into coding.

I have never read this, linky please
Considering PSPUAE is in usermode anyway, I cant see why it would'nt work.
Alot of games call kernelmode PRX's in usermode.

Strange, I'm pretty sure I found a couple of posts saying such a thing in this PSP-Hacks thread only yesterday. Yet I can't find the posts anymore. They must routinely delete posts every now and then.

And now the new word is that SNES9xTYL 0.4.2 can be signed but still not work apparently, thus rendering the issue pretty moot.

Wish people would make their minds up!

Indeed.

Looking at the code now, It looks as though the sound is being run on both Main CPU and ME CPU. Did'nt notice this before, must have been so PSPUAE obsessed that I missed it.

Running both at the same time would'nt improve any speed at all, in my opinion. So, I will maybe look at disabling sound completely on Main CPU.

Only problem is, I have to remember how the hell I done some of the code,

Good luck with that!

BTW, not sure if this was already asked before, but what's the likelihood of IPF support being added in the future? Did you speak to the SPS guys about it? Not too sure what requirements (if any) one has to fulfil before you're granted access to the source code.

SPS wont work on PSP, as far as I can see it only supports WinUAE and linux.
Doubt they would give the source out.
I aint checked of late, didnt see the point already code loads of stuff on the to do list,

You could try asking this guy to see how he had to charm them.

When he says, its done.
Then I spose we could ask.

Offtopic, sort off.
For those stuck on firmware 6.31 and 6.35.
Theres now a downgrader, to downgrade to 6.20, so you can use 6.20 TN-C HEN.

It may work on higher 6.36 / 6.37 FW too, but I cant confirm. Its signed so you dont need to hack your psp to use it.
If you do decide to do it, make sure you pick the right 6.20 update, as there are 2 types.
One for the Go! and one for the normal UMD PSP's.

Does the Amiga emulator for PSP support extended ADFs too? or only "regular" (ADOS or NDOS without error protections) ADFs?

Hmmmm, I feel invisable on these forums.
I answer things and people rather ignore me.

From memory about 3 years I did run an extended ADF of Turrican.
If they dont, then let me know.

That's the weakness of forums - skip reading rules and people (including me!) miss stuff all the time! Feels like this ->

Sorry FOL, I was reading this thread only and didn't notice anything from you about extended ADFs...
Could you please remember me/us your main links? Website etc.?

http://www.pspuae.com or http://www.ultimateamiga.co.uk
Both are same site, merged with a few other sites on my network.
