Re: Audio Playback Issues

Yup, thanks for the tip, that seems to have fixed it. Pity the update script doesn't also update the kernel headers. Still getting some weirdness with how long it takes to release the audio device after playing 16bit 22050hz mono wav files, but that may just be an issue with aplay, and I don't have ...

Audio Playback Issues

I've trying to work the pi into a Steel Battalion controller for my 3yo nephew, who is obsessed with buttons and levers (currently wants to drive a train when he grows up). At the moment I am looking for a simple way to call different audio files for each button pressed (of which there are lots). Ev...

Re: AdvanceMAME Controls

*Shrugs* It wasn't not working, advmame just can't see the events being generated except in raw mode. No idea why... well none worth the effort of testing at least. Don't know if you have seen this blog post . Similar to what you have done, except in C not python. Had I been aware of the uinput modu...

Re: Coin Operated Arcade Machine (MAME)

I haven't done much over this weekend, mainly just fiddling software and sanding. Since its probably not a normal thing for a MAME cabinet to have, I thought I would show you my rear panel. http://vps.verbicide.com/MAME/IMG_2378.JPG For maximum flexibility, I have mounted a panel with connections li...

Re: Coin Operated Arcade Machine (MAME)

That's more or less what I just did, though splashy is still refusing to actually show the splash screen on boot. I'm still getting a few lines of text, despite the quiet option though. Boot time (to login prompt) is only a few seconds, so it probably won't matter much. Looks like most coin mechs us...

Re: Coin Operated Arcade Machine (MAME)

I'm running debian. Having it load strait into an arcade front end without having to use the shell shouldn't be an issue. Getting a splash screen to replace the loading screen should also be possible, I've been thinking about trying it, but there are one or two steps that may be trickier with pi tha...

Re: Coin Operated Arcade Machine (MAME)

I'm building an bar top cabinet. Give yourself plent of room, you probably won't have the same space constraints I have, but several times I have run out of space and had to redo parts to make things fit. If you do decide to use GPIO keys (I wrote my own module), you may run into the same issue I di...

Re: AdvanceMAME Controls

Its an interesting module, but it registers with the input system as a keyboard, and I want to register as a joystick.

AdvanceMAME Controls

So I build some controls, hooked them up to the GPIO port and written a kernel module to interface with the input/joystick subsystem. The issue I am having is that jstest can read the controls fine, but advj detects the controls, but is unable to read them. ie it shows the correct joysticks and butt...

Burnt Pins

Lucky me, looks like I have managed to burn out two of my GPIO pins. Just wondering if anyone else has been as lucky as I have.

Re: Advance MAME (Findings so far)

I had the same problem initially, but my card is only 2gb, so I mounted a usb key and compiled the source on that. I'm guessing you have not successfully increased the size of the partition. If you login to your pi and run df, it will list the mounted partitions, their sizes and how much space is us...

Re: Advance MAME (Findings so far)

I have a PAL/NTSC LCD TV, that is the target screen I want to use. Sadly, I have not yet been able to figure out a configuration that will actually let these games run when connected over composite. I keep getting a video mode error when trying to start the games, or advcfg crashes during the test w...

:-) Both work fine for me. Can't compare Bubble Bobble (it seems fine though), since it won't work on my laptop :-/

Re: Advance MAME (Findings so far)

For me, invaders and 1943kai both play the same on my laptop as they do on the Pi. With asteroid, I had to drop the sample rate down to 11050 before I got it to play and sound correct (there is a colour difference compared to my laptop though). In starwars I can get the sound working, by dropping to...

Re: Advance MAME (Findings so far)

I found lowering the audio frequency in mame to 22050hz fixed the weird audio issues I was having, and also improved general peformance. I'll try some of the roms you have listed later to see if it has a similar effect for them.
