Re: Is this the possibility of a Power VR SGL Wrapper?

Posted on 2017-01-13, 03:15

I'm sorry for quite (yeah, right...) long absence and all this delays, that year was really painful for me... anyway, alpha preview will be released on late february/early-mid march. I've got Mechwarrior 2 PowerVR Edition, just need to get it working on more modern operating systems (any help from …

New registers discovered, this time including target framebuffer phys addr and other important things. A few, simple tiles blitting test shown on image, click for full size: http://redtux.rocik.net/projects/powervr_reveng/PCem_SGL_1_small.png Dimensions might not be correct, because it's blitted in …

It's not done yet, but I'll just implement software rasterizer from scratch that works like PCX2 after reverse engineering meaningful registers. There is no point in using OpenGL or another API combined with host GPU as a renderer (although it's of course possible), for this I have my wrappers that …

Nah, I just made a byte order typo in only one of the PCI configuration space header field, so lame of me. :D Actually, apart from PCI configuration space it detects which type of card is it by reading two R/O registers which are used by driver before initializing card. After detecting which PowerVR …

It behaves like that because you did not emulated this card, only faked that it exist... anyway: I managed to get SGL and Direct3D to work on my emulated NEC PowerVR PCX2 card! :) :) :) I mean, holy shit - it works! Driver no longer rejects my card, null rendering for now (shows only garbage from …

I got SGL to work in Windows, and wrote some simple code with it: https://www.youtube.com/watch?v=azfQHgUKOrk Do you have the SDK? I believe it is posted here on Vogons somewhere. I can give you my code, so you can play around with it (Visual C++ 6.0): https://www.dropbox.com/s/2ir10zpnbp27lj5/SGL. …

Regarding my previous post... So, vetz donated PCX2 in order to help development, so I would like to publicly thank him for this generous gesture. Thank you, vetz ! :) For now it helped my NEC PowerVR in PCem emulation to become more mature because I could do a basic reverse engineering in order to …

anyway here's the reason why i've bumped because now i've lost 3 nights to this so far if someone picks it up that's fine if someone doesn't pick it up that's fine how's an "infinite plane" span going to work anyway Hah, I see that you did the same what I have done some months ago - PowerVR support …

Is anybody interested in alpha preview of my PowerVR wrapper? It would support only two games for now, Virtual On (no overlay) and Biohazard (fully working), the rest will be not only unsupported but intentionally or unintentionally completely not working. Is it a good idea to release this preview …

Is there a remote possibility of some work on this and/or s3 wrapper during jul/aug? Actually I came back to my hometown for almost 2 months (jul/aug), I have some discretionary time also all my devices and tools are here so I can work on it! I've bought S3 Virge/VX (Elsa Winner 3000-L) specially …

About Virtual On, maybe I'm wrong but aren't those center blue bars and upper energy bars supposed to contain some text/numbers? Of course, as I wrote in the video description those are a part of overlay rendered by DirectDraw, which is (mostly) unimplemented yet. Solid bars are rendered by SGL and …

Dude, you rock! Is this aimed towards modern systems or will someone be able to use this on a suitably retro PC (something beefy with a Pentium 3 and GeForce card maybe?) ? Sorry for late answer, but I've tested my wrapper on quite old machine with AMD Athlon 600MHz (Slot A), 128MB RAM, NVIDIA …
