not that any of these would work with an existing mythtv setup :) (a myth frontend on psp would indeed be kinda nice ...)

gcc hosted on a device with 32mb memory and no swap ?

great =D i bet you can even compile hello world with it =D

Keyboard input:
The best input method would probably be voice recognition.

totally. very useful on the train :) *giggles again*

Fair statement :) however if someone was emulating say Dos or Mac OS. a keyboard would make it a fully fledged computer.

a fully fledged computer with roughly the performance of a game'n'watch, yes =)

Sony might not use the IRDA port, but it's used by a TON of homebrew folks. We have programs that use it as a remote control, programs that access your cellular phone, programs that transfer data between PSPs, and many programs now support IR keyboards. Everything from Quake to IRC apps are using a...

Removing the IRDA port from the slim was the worst thing Sony has done.

you mean removing a port that no official software supports and in turn adding another (tv out) that all software can use out of the box was the worst thing they could do?

i don't think so :)

haha :)

i'd totally love to hear the story about HOW this stuff was reversed :)

hooray! i remember this one :)

assembly, c, c++ ... all of them. and choose something MUCH smaller for your first project =P

i'm starting to wonder what kind of demanding/huge project you are planning to port that you are fixing all that stuff ... :)

use fflush before fclose ?

its not telling me what line at all

you should try both kernel- and usermode adress, eg when EPC=0xxxxxxx then try 0xxxxxxx and 8xxxxxxx aswell

compile with -g, then use psp-addr2line with the EPC adress to find out where it actually crashes.

also for random crashes that have no obvious reason the usual suggestion is to look for alignment problems.

hehe...the fourier transformation you would need to do an "equalizer" type of visualisation. (although if all you want is visualisation you can get away with simpler, not terribly accurate, stuff)

thats pretty trivial, something like that:

for(i=0;i<size;i++)
{
putpixel(i,halfsize+(audiobuffer/somefactor));
}

do that after every swap of the audio buffer and you'll get something like the scope visualisation in xmms/winamp

listen to what weltall said, such behaviour is almost certainly caused by some alignment problem.

Or the best option is to upgrade your 1.5 to Dark Alex's 3.03 OE-A (then upgrade to OE-B). This provides all the abilities of 1.5 with the added bonus of running the 3.03 firmware so almost all current games will run fine.

i'd rather not use anything that touches the flash... devhook is fine =)

dont worry about the page flipping stuff, if i recall correctly from gc-linux the linux framebuffer drivers dont directly deal with it at all (i remember trying to put a efb->xfb copy into the pageflipping routine, which i couldnt find at all =P). that said, since the psp has a common pixel color fo...

as long as you arent try to push yourself into their market (read: pirate their games, or create and sell unlicensed games) i pretty much doubt sony even remotely cares.

i can't see how kxploit would be illegal, even if the dmca would even apply here (which i doubt) then the interoperability exception would still be there, and allow you what you are doing. i won't be worried at all.

cool, so the missing bit diving into the gpio driver eh? =)

learning by doing, many of us for more than one (or even two) decade(s) =P

many psx homebrew programs were either created with psyq (the official sdk) or net-yaroze (which is gcc based, but the created programs linked with libps still can't be given to any non yaroze member). that said, ofcourse psx software can be created completely without official tools aswell, there is...

If so
does this mean people can actually compile the PSPSDK nowadays
on non x86 machines? (like maybe a mac powerpc running linux or
on a sparcstation running linux).

yes

i would suggest to simply forget pspe...it will run hello world, and maybe a few more trivial apps - but thats pretty much all about it.

why do you think that matters to anyone involved in homebrew stuff at all?

maybe this is something like "locked cache" on ppc?

tried mailing the ePSXe author(s) ? thats what i'd try anyway =)

i have messed around with writing stuff to the scratchpad, and it didnt affect anything (atleast i didnt notice =D) and the data i wrote there also stayed unmodified...

but yeah its true, its not usefull for speedups (like it was on good old psx) :/
