Re: HDMI-VGA Adapter with chip GBP 12, free shipping

I came across the same adaptor. I've tested it at 1920x1200 and it works pretty well. The picture quality is not amazing, but it's acceptable. I made a video demonstrating it here:

My config.txt is:

hdmi_group=2
hdmi_mode=68

Hmm. Seems like whoever is handling these things at RS is not doing a very good job, to put it lightly.

Re: Poor support from RS

Same here, although I realised it was my mistake because I clicked on the EU power supply instead of the UK one. Easy mistake to make. I e-mailed them immediately after making the order to see if they could change it, but they never got back to me. They will accept returns but it's probably easier t...

RS sent me 2 Raspberry Pis by accident

RS sent me 2 Raspberry Pis by accident. It seems they duplicated my order because they also sent 2 power supplies too. They were dispatched them in separate packages, at the same time to the same address. The invoice numbers are the same for both. I've e-mailed them about it but no response yet. Som...

Re: Compiling and running OpenGL ES programs

It has just dawned on me that these drivers don't have any integration with X yet, do they? That would explain these problems. Guess I'll have to gut out all the X stuff and make it work with the framebuffer only.

Re: MAME bartop arcade

I've been trying out AdvanceMAME today, some games run OK such as Galaga, Gaplus, Burger Timer, but some games run too slow and have stuttering audio, such as Galaga 88, Donpachi, Gyruss. Hopefully I can find some way to get a more optimised MAME so these games can run well.

Half the memory? I don't see how it needs that much. A 1080p 32-bit framebuffer is less than 8MB.

Re: Memory size is wrong?

According to /proc/meminfo the memory size is reported as 125004kB.

I thought the RPi was supposed to have 256 MB of RAM? What happened to my other 128 MB?

Re: indie arcade machine with RaspberryPi

<t>I agree with Jessie. JAMMA is an obsolete standard from a bygone era. The only benefit to using it would be to reuse old cabinets. It was only useful because every game had its own custom hardware, but this is no longer true once hardware became a lot more powerful and commoditised.<br/> <br/> I ...
