Yeah, I am sure that a lot of coders have written those tools, but they do not seem to be public for the most part.

Still, there's tons of such tools here. Only use search function with "BMP" or "PNG" and see what it spits out. IIRC the earlier ones by seanser compute really long, no idea if newer versions work faster. But guys like algotech, fieserwolf or Burglar normally (way more often than myself) halfways know what their doing.

How about https://csdb.dk/release/?id=143029&show=notes#notes

Of course as gpz already pointed out if a PNG/BMP/whatever shot includes sprites and violates KLA/MC restrictions, it won't work properly. Workaround: BEFORE making a VICE screenshot ALT+M (Vice Monitor) >$d015 00 -> sprites off ^^

This tool here might also be a good start:
Vice Snapshot Grabber 4.5
It extracts the current screen (in 'whatever' mode) from a vice snapshot file.

And that will works exactly as bad as the builtin koala snapshots :)

Just for info - i just comitted the new/fixed screenshot code, so with next nightly build you can make those koala screenshots directly in VICE. Let me know of any remaining bugs :)

@TheRyk,

Thanks for suggestion, but that doubles my job. First conversion PNG to PRG, then PRG to KLA.

@Groepaz,
Thanks for making WinVICE fixes.
I have big problem using WinVICE 3.4 on my Windows 10 laptop. Problem is so annoying - WinVice just quit working after a while, and that lasts between 1 second and 10 minutes. WinVice doesn't give me any error messages, just quit by itself! Really annoying to take game screenshots that way.

@All,
I already took around 300 game screenshots, all games have between 4 and 10 shots. It will be so much more if I don't have that big problem with WinVICE.
Decided to keep game screenshots them also in BMP format, not just in KLA format.
Why? I want to post them to GameBase64 crew to implement them there. There are soo many games (for example Cinemaware games, Turricans, Mayhem etc.) that deserve much more pictures than they have now. My BMPs are in 320x200 resolution, same as GB64 has.
If someone from GB64 crew read this (or you know someone there, please, tell them), please PM me.

Is that official VICE 3.4 you are using, or a recent nightly build? A lot has changed since the 3.4 release, maybe the issue you see has been fixed already if you are using 3.4.

@TheRyk,

Thanks for suggestion, but that doubles my job. First conversion PNG to PRG, then PRG to KLA.

Pixcen V0.7.0.28 (and probably a bunch of similar tools) offers various conversion options just via "LOAD" (Import .PNG/.BMP as... Multicolor) and "SAVE" (as... -> Format/File-Index .KLA). No need to use .PRG at all.

If there's sprites, however, which most games will have, chances are, there are clashes as plain .KLA restrictions (3 colors per tile) will be violated by Sprite overlays, so you need to fix these clashes manually (if you didn't turn off sprites before snaphot)
