A while ago over at MobyGames, AppleWin NTSC was recommended (okay, by me) for obtaining Apple ][ shots. However, it's a bit of a pain to use, since the built-in screenshot function doesn't work. Also the NTSC output is still not *quite* ideal (there's some ghosting/ringing going on, and black/white areas are somewhat 'noisy').
Thankfully Michaelangel007 has provided a newer build which addresses both of these issues. The full discussion is on github, but here's a quick-start guide to make your lives easier and your screenshots better:
- Grab Applewin.exe here (feel free to *rename* it and drop it into your AppleWin dir).
- Run it. You'll want to be in TV mode (cycle through with F9), with "50% scanlines" disabled.
- Hit PrintScreen to capture a .BMP shot in the same path as the disk
There's still some post-processing to do however. For some reason, the rendering in this build is rather blurry - luckily this is not hard to fix, since only every *other* scanline is interpolated (so no image data is lost). Plus we still get a border, which we typically don't want.
To do it all the easy way, and convert to .PNG while we're at it, I use this simple batch file with ImageMagick:
Save as .bat in a folder with all your BMPs, run it and you're done. Note that the original BMPs will be deleted, and of course you'll need the PATH in your environment to point to your ImageMagick directory (or just stick the path before 'convert' above).
Here are a few results (click to enlarge):
These improve on the previously-available AppleWin NTSC, which itself is already much more faithful than other emulators out there. Hopefully a version of this (without the blurry, cross-scanline interpolation) can be merged into mainline AppleWin, and adopted by others -- maybe then we'll stop seeing plain wrong shots like these all over the internet.
