Re: [Suggestion] Internal GLSL Shaders from DOSBox Staging

You can already load many varieties of retroarch's CRT GLSL shaders (including chaining presets!). Making them internal won't be more practical. also that's a very bad and misleading "real CRT" shader example since it doesn't take in account for VGA's doublescanned modes (among other things like ove...

Re: PCEM Skin Wrappers?

It'd probably be hell to implement in Wx, but (in theory) it's possible to write a GLSL shader that downsamples the output image and overlay another image on top as specified from a .glslp file. Extra immersion would probably require more shader variables for the num/caps/scroll lock and HDD/Power/T...

Re: Raspberry Pi - Top configs

It's still all a big "depends on what you run" On v17, a stock Pi4B with cooling can get 100% with an AM486DX4 90MHz+S3Trio64+SB16(DBOPL) on most things i've tried, however VC6's still slow with regards to texture uploads on OpenGL, so the software renderer's still the best to use.

Re: Daikatana & Voodoo1

GLSetup was a video driver installer made more to answer Q3Test support emails (as many of them involved Voodoos at the time, and there was much mixed language of what OpenGL meant etc..no thanks to minidrivers).

Re: Daikatana & Voodoo1

You'll have to go into current.cfg and change the gl_driver line to 3dfxgl manually. There's many OpenGL games that don't bother enumerating the Voodoo1/2 (...by assuming from presence of glide2x.dll in many cases which is a bad practice) and switching appropriately to their ICD.

Re: two questions, one about arm, one about widescreen

1. Yes. There is an ARM dynarec
2. Win2000 drivers for Banshee/Voodoo3 cards do have some widescreen resolution support, but that's way out of the usable scope for a Pi that can only handle a 486SX consistently at best.

Re: Problem with Voodoo Graphics in Interstate 76

It's real behavior believe it or not! I76 doesn't know what to do with >2MB texture memory. It's one of those Glide games you should tick that 2MB checkbox for (in the 3dfx driver panel). And if that fails, use a Voodoo Graphics instead (with a 2mb+2mb configuration)

Re: Issue intstalling Windows 95

I can think of two possible reasons...

1. Your CPU's too fast for Windows 95 (>350MHz)

2. The bootdisk being used to install is possibly infected with a boot sector virus sabotaging a fresh install immediately. (FIC VA-503+ would warn about this)

Re: Why is accessing a physical CDrom so slow ?

I almost think it's PIO transfer mode on the host machine, which Windows can sometimes inadvertently.turn on when it has trouble reading a cd (which can happen with some protected CDs) and can be very tricky to reverse. I personally use CloneCD/VirtualCloneDrive when dealing with my protected games.
