CachedBitmapUtility about x8086netemu HOT 9 CLOSED

I'm no longer supporting the FastCGAWinForms class.
However, here's the referenced library: https://github.com/svejdo1/CachedBitmap

from x8086netemu.

Unfortunately, the Console class in .NET is awfully slow.
If I'm (we're) ever able to fix the bug(s) I'll try to implement ncurses support.

As for the WinForms version: it is quite fast, but there's a lot more that can be done.
Enabling this hack makes the video renderer run blazing fast.

If you decide to experiment with this hack, you'll need to comment line 276 and uncomment line 277 from the CGAAdapter class.

Do you have a newer version that hasn't been published to here?

from x8086netemu.

Yes, although it still suffers from the same bugs mentioned in the README

Would you mind updating the branch? I'm very interested in helping out on this project. I've also commented on your blog regarding your frustration with "overflow checking" with a possible solution/explanation. I see that what is published here still has overflow checking enabled and I'm guessing that you wrote additional code (with additional overhead) to work around the issue. I suspect that there is an opportunity here to improve performance by utilizing the compiler feature instead of these workarounds.

As for the "same bugs" problem; two eyes are better than one. ;-)

With the current code available; remarking out the line:

ug.ScaleTransform(scale.Width, scale.Height)

In RenderText() of FastCGAWinForms allowed me to get the WinForms version up and running.

It appears that ScalTransform has been removed from the CachedBitmap project. I'm not really sure what affect this has; however, the WinForms app appears to work as desired.

Also, it's interesting to point out that the WinForms version seems to run a lot faster than the console version. So well worth the effort in getting it up and running.

Without a doubt, this is a project that has be very excited! Awesome work thus far. I really look forward to participating going forward.

Hah... removing the reference from the project was all I really needed to do. ;-) With that said, now that it's confirmed we are both working with the same code... I'll definitely start digging in. Thanks for the additional links... will explore those further as well.

Couple of hints:

1. Edit and QBasic appear to suffer from the same bug. (Not sure if it matters, but FreeDos' Edit and GWBasic work just fine)
2. Defrag fails with a rather interesting error message
3. CheckIt's "Tests->System Board->[CPU Interrupt Bug](https://www.google.com/search?q=checkit+cpu+interrupt+bug" test used to work; I don't know what I changed to break this test.
