Cen64 Developmenr for MIPS based platforms

Post by forphucksakes » Wed Jan 21, 2015 12:14 am

Hi Guys,
Not sure if this is the right sub-forums but here goes...
Found your page while looking for emulators and was wondering if Cen64 could be run on the following MIPS-Linux devices:

ImgTec's creator CI20 :
http://elinux.org/CI20_Hardware#Tech_Spec_overview
https://github.com/gcwnow

GCW-Zero :
http://wiki.surkow.com/Quick_Start_Guide#Specifications
https://github.com/MIPS/CI20_linux

The GCW-Zero does have open source gfx drivers for its Vivante chip via etnaviv:
https://github.com/laanwj/mesa/commit/f ... a39e470a9e
https://github.com/etnaviv/etna_viv
Which is capable of OpenGLES 2.0 :

One "issue" with the GCW zero is that its LCD's max resolution is at 320x240 which I guess would need rescaling since(correct me if I wrong) the n64 VI enforces 640x480 output(though that wouldnt be a problem with its HDMI out). It also only has a 1Ghz SoC though with overclocking it could be pushed abit higher.

The CI20 on the other hand has a dual core 1.2GHz SoC + 1G DDR3 w/ PowerVR graphics. Currently everybody and their uncle seems to be obsessed with Android development which is quite sad especially considering that there are some very capable devices out there running on linux and not Dalvik(like the open pandora). Unlike Openpandora though the above devices are not ARM based and instead are MIPS based(like the N64 itself)

GCW-Zero forums/IRC :

THanks & regards,

As much as I love MIPS hardware...

Just because it's a MIPS platform doesn't make it useful for emulating N64. :p

If somebody were to do it, you'd need to essentially write a VM because a lot of N64 software runs in supervisor mode. And you'd still need to emulate the RSP somehow, which would be quite difficult on a low-power device like that. I can't see anything better than HLE running on it.

Hi Marathonman,

Thanks for the response. I appreciate it.

Yeah I figured cen64 would be a longshot being a accurate simulator and all but I thought i'd put it out there. What kind of SoC + board specs would you expect as a minimum to be able to run CEN64?

Regards,

CEN64 is a dog. You really only get decent performance with an aggressive OoO processor @ 3GHz+.
