in your retroarch.cfg file, scroll down to where it says

Code: Select all

# audio_driver =

and change it to:

Code: Select all

audio_driver = sdl

(make sure to remove the hash symbol)

This page takes exactly 3 seconds to load for me. 5 seconds without overclock. Is your internet connection fast on other computers?

portets

Can you get a different volt meter? 5.94 could be enough to break something.

portets

I'd be interested in people experimenting with each of the values in the overclock (arm_freq, core_freq, sdram_freq and over_voltage). Try reducing each of those back to stock and report which of them is critical to the corruption occurring. Also if you can try on more than one sdcard - possibly so...

My pi also seems particularly sensitive to overcurrent. I'm using a high quality regulated 5v bypassing the polyfuse as well. Tested overclocks using quake3 and compiling various programs. no overvolt: arm_freq=990 sdram_freq=600 core_freq=450 with over_volt=6: arm_freq=950 sdram_freq=500 core_freq=...

portets

Do you have access to a volt meter?

portets

I've noticed in other applications that the sound backend can be chosen in run slower with SDL sound. ALSA is way faster but has terrible popping that'll hopefully be fixed soon. I think the quality issues with ALSA may only be on the analog out though. You don't have to modify config.mak to enable ...

A couple people were working on a port a while back, but it's been a while since anyone heard from them(to my knowledge).

Best wait I guess.

ps1 emulator is working though.

What're you wanting to do?

Here's a good python 3 tutorial: http://en.wikibooks.org/wiki/Non-Progra ... r_Python_3

Aug 05 commit appears to have fixed my issue.

portets

I'll have to check that out. But shouldn't the older start.elf files also not work when immediately replacing the current one? They're the same size, so I assumed the file would occupy the same exact spot as the previous file if copied after deleting it.

portets

Been gone for a few days. Great to know it's working good for everyone.

Will have to check out the new changes and thank notaz for this!

This contains the executable as well. Don't know all of the dependencies though

I don't upload things much. Where would be a better place?

portets

Yeah, just checked. Overscan settings are definitely applied, but framebuffer size isn't. Doesn't matter where things are placed in the config file. Empty config file doesn't boot either. With and without the two new cmdline.txt arguments, doesn't matter. And the status led's on-board all behave com...

A new version of PCSX-ReARMed was released that adds an SDL port. Figured I'd try getting it running. Just a little modification and so far we have:

Kind of slow, but almost playable with frameskip. Just hoping I can get the gles gpu plugin working.

portets

After unplugging my pi the latest firmware fails to boot. Rebooting was fine before I unplugged it. As does rolling back to previous elfs. No combination of config.txt or cmdline.txt parameters appears to affect this. Tried redownloading the elfs myself to no avail. The rainbow screen comes up, is r...

Wow, don't know if it's just my sd card or what. Going from the july 25th raspbian untested repository update to this significantly reduced boot time for me. About 8 seconds shaved off. Boots to desktop in 33 seconds, down from 41.

I got extremely lucky

. Stable for me with no overvolt and thorough testing:

Code: Select all

arm_freq=990
sdram_freq=600
core_freq=420
gpu_freq=280

And no, there are no typo's there. My ram could be clocked higher, but dom said the sdram_freq currently maxes out at 600.

portets

The gpu should be equal to or half of core speed. Or 1/3 of 2x core speed. example: core_freq=420 420 x 2 = 840 840 / 3 = 280 gpu_freq=280 arm_freq is the cpu, core freq is something related to the interaction between the gpu and cpu. Core freq also changes the cpu's l2 cache speed. Your gpu_freq is...

I'm going to try overclocking tonight and would appreciate a little advice. This thread is a bit long to find what I'm looking for easily! So, to overclock I just use "arm_freq" to set the cpu speed to ~800mhz (as a starting point)? Yeah, arm_freq=800 is a good starting point. Remember over-volting...

portets

We're busy benchmarking at the moment against a bunch of A10 platforms, and while CPU is a bit of a wash, we're still streets ahead on graphics performance.. I assume you're optimizing with compiler flags? And with the gooseberry people playing dirty, are you testing with an overclocked pi? ;) (I h...

Someone else is working on x accel, maybe you could work with them? http://www.raspberrypi.org/phpBB3/viewtopic.php?t=4649

Open a terminal and type:

Code: Select all

pcmanfm --desktop-pref

under the desktop tab, uncheck the box.
