The fourdo.com site has been moved to new web space.
Now that the move is complete, I’ve added a both a forum and a wiki. I don’t have particularly grand plans for either of these, but here’s the immediate main use for each of them:
- Forum – Bug reports and investigation
- Wiki – Game compatibility list
If you are interested in helping me out by moderating either the forum or the wiki, please let me know using a private message in the forums.
jonny, ia want to be a beta-tester of 4do!!!
Beta testing is ongoing and open! You can download 4DO and leave feedback or report bugs on the 4DO forum. Thanks for the interest!
Johnny, i want to tell you about some bugs of emulator, wing commander 3 dont work correctly, there are bugs in colours!
ps sorry for my bad english, because iam not english man. =)
I have noticed this bug too. It would appear to be a FreeDO Core bug because it happens even worse in FreeDO. I will add this to the compatibility wiki.
The new year soon, the best gift of course the emulator))
I was wondering if you planned to develop the emulation for the following things (of course with lower priority compared to the bug-fixing!!!):
– light gun (emulated through the mouse)
– playing Audio CD through the 3DO’s main interface
By the way, it’s long time you don’t publish a new version of 4DO! 🙂 Why?
Thanks for your excellent work and happy new year.
I believe an attempt was made to actually get Audio CDs to play through the emulator, but was not successful yet.
No Idea about light guns though.
I would like to get light gun support added. I also want to get flight stick added. I’m unsure how successful I’ll be with this. I’ve asked around for anybody that has either one of these. If there’s a game that has a control configuration screen that will inform the user that “flightstick was just plugged in” or something, then I’ll be able to spam the input buffers with random bits in hopes that I figure out what the exact match is for the device.
If this avenue doesn’t work, I would have to try to disassemble 3DO code. in which case it may be so hard that I give up.
I was able to figure out the correct input bits for the “gamepad” support by disassembling and debugging FreeDO. It took a while but I found it! However, FreeDO never supported the flightstick or lightgun, so this isn’t an option.
Alas, I tried for a while to get audio CD support working. I assumed it would be pretty simple once the BIOS was working. Some reason the bios didn’t react at all to the presence of an audio CD. I get the feeling it’s not going to be that easy. I suspect it was due to incomplete development on the CD drive emulation in the FreeDO core. So, I think it would take a focused effort, and I doubt it’ll get done unless someone else hops in to help.
Hey, just an FYI for those interested, I’ve picked up work again on 4DO after the new year. I had a bad wave of work for a while there.
Hi John. I am very glad that you came back. Work awaits the competitors do not sleep)))
Explain why you removed the option to adjust the speed of the processor with the source of the project FREEDO 2?
And you come up with something with a screen? at the moment the emulator displays 60 frames, and progamma to record video games (Fraps) show as many as 2000 frames.
People on the load card overheat. Why such a burden at all on the video card? – It means the calculation of the image is the processor, carefully studied the key problems please.
And yet …. I like it asked you to come up with something in the derivation of interpolated images.
At this point you have 320×240 stretched to fill the screen when switching to full screen.
Why do not you do normal interpolation frame?
Make at least scale
Keep up your project and wish you very good luck.
Hi Sedabi, I appreciate the feedback!
Regarding FRAPS and the high FPS (more than 60), I believe I have a solution to the problem. The DirectX rendering logic I had in previously was lazy and rendering in all available idle GPU time. I have a change checked in that will get I’ll be releasing soon.
I do not know if or when I will add any features that take advantage of the processor speed setting that was on the latest versions of FreeDO. I haven’t looked into the details of how I should add the feature. But, I can at least let you know that I know the feature you’re referring to.
I have looked into doing 640×480 rendering before, but this performs poorly. This is another feature I’m not yet sure how to work into 4DO. This is due to “software rendering” being slow. I suspect I will probably not add this feature. Ultimately, I hope that Altmer completes a prototype with hardware-accelerated graphics and someday chooses to share it with me. 🙂
