Hi thanks fo reply!!, im in DOS, using for playback, quickview pro

- Picogus is in USB mode
- Video is a Cinepack 12fps, 320x200 video, tried ADPCM 22khz mono audio or PCM 8bit 11khz, interleave every frame. Video is 40min long, 560mb, then 230-250kb sec
- Tried too msvideo 1 256colors, 12fps, same audio options and interleave, 640mb more or less 270kb sec
- Tried iso and cue/bin

Bot videos i burn in CD and test in a 4x IDE drive and play fine, from HDD too

Using Picogus CD give me stops every 2 or 3 seconds because frameskip

Hi! i get consistent 600kb sec transfer rates in speedsys, and i can confirm by copy a file in DOS is correct

The attachment IMG_20260414_092524.jpg is no longer available

In fact my IDE 4x drive is slower, because i think i use CDRW unit and the unit is old, read at 360-420kb sec, but anyways video play smooth from real CD

I dont have a IO recovery period option in bios

thanks!

I wonder if the MKE cdrom has naturally higher CPU overhead and its running out of CPU power to copy from ISA bus and decode at the same time

I tested in a pentium 200 and videos are slow too using picogus

Funny thing is that msvideo1 avi play smoth from HDD in a 286 25mhz

Maybe is ISA bus that saturate?

The only videos i can play smoth using picogus CD is msvideo1 optimized for CDrom playback at 150k

Im testing more cd emulation, and at least in my motherboard?¿ can someone help me to test, i think is very cpu consuming

Im testing game The DIG, this game need a DX/2 66, i have a DLC33, of course MUCH slower than minimum, but anyways, if i play from HDD or IDE CD, the game is a little slow, but playable. Using Picogus CD emulation, in USB or SB mode, is same, the game became unplayable, too slow

Any ideas? or is just picogus cd emulation that consume too high CPU?

thanks!!!!

Are you playing the game in DOS or Win9x? If it's in win9x, use the latest firmware version and swap to the microsoft MKE drivers instead of Creative. The Creative MKE driver blocks the CPU like crazy.

Also because the MKE interface doesn’t use IRQs or DMA it does burn a lot of CPU time polling and transferring data.

The game calls for a 486DX2/66 and 2x speed CD-ROM under DOS, you would think that means it's fairly safe for an MKE drive

thanks, i had similar problem with my 1x mitsumi cdrom until change driver to one using dma

But you say the problem is interface no driver then? no solution with diferent driver or parametes?

thanks a lot

Hi everyone! Quick question as I plan to play some x-wing this weekend! I have my PicoGUS in USB mode and use a hub with my USB drive attached with my CD images. This all works fine. Then I also attached my Logitech Extreme 3D Pro joystick. I see on the PicoGUS wiki that "joysticks" are supported and maybe this is where i'm getting confused. I enabled joystick support (pgusinit /joy 1) but I see on the wiki that only xinput or sony gamepads are supported? So not strictly 'joysticks' but more gamepads? unless there are joysticks that also support xinput? I'm no expert hence why i'm asking here. I read that my joystick uses HID.

So any clarity on the matter would be much appreciated. All I wanna do is fly my x-wing!!!!! 🤣

As far as I know, the PicoGUS's joystick support just doesn't work with DirectInput devices like your Extreme 3D Pro. One solution would be finding a PS4-compatible Thrustmaster T-Flight HOTAS or similar, and hope that the three buttons and axes that you need end up mapped in a way that you can fly with. If you can find an analog joystick like a Gravis Analog Pro for a good price (I see two on eBay right now for under $30 CAD), you could also use a cheap sound card like a SB PCI 128 with its DOS Sound Blaster emulation turned on, and make sure that you set X-Wing to use the PicoGUS for audio.

If it's X-Wing Collector's CD-ROM (1994), I'd recommend:

-Set the PicoGUS to GUS mode, on something like Port 240, IRQ 5, DMA 1/1, and disable the joystick
-Set the PCI 128 to Port 220, IRQ 7, DMA 3
-Set X-Wing to Gravis Ultrasound for audio, and enjoy!

If it's the original floppy release of X-Wing, this could get a bit more complicated since I don't remember if it had native GUS support or not. In that case, choosing the Port/IRQ/DMA values in its installer is a bit more tricky, I can't remember if it allowed for direct selection of the Sound Blaster settings although it did have SB Pro support but not SB16.

So, short answer; you'll need some more hardware, and some resource juggling, but it's possible!

The next release of PicoGUS should have a pretty big overhaul of joystick support, so Directinput joysticks should gain support. I'm currently pretty deep in PicoIDE and dayjob stuff so I don't have a definite timeline, but sooner rather than later!

If you want someone to test out the DirectInput functionality, let me know! I have a trio of USB sticks (Microsoft Sidewinder Precision 2, Logitech Wingman Force 3D, Thrustmaster T.16000) and a desire to play various space combat/vehicle games in DOS.
