Yup - colour generation is now based on the same algorithm that was used to generate the Olivier palettes, and PAL palette quirks (the thing missing from OlivierP) are also reproduced.

Btw. could you include this and the NTSC version with the next version of the emulator?
May I ask for what reason? The default colors in the new WinPLus are already more exact than the Olivier palettes, especially the PAL one.

Especially palette functions are brand new and it seems that they have removed an option to adjust colors of external palette.
The function is there - check the "Display settings -> Also adjust external palette" option in Atari800.

Not really - other web resources seem to concentrate only on archiving only Atari software, not "everything but the kitchen sink" as on Pigwa.

The previous example i got hold of was from the "ftppigwa" site and I am quite surprized it was indeed faulty - I understand they have an excellent reputation among the atari community.
It's just an FTP server with bunch of stuff gathered from those old CD collections that once circulated among the Atari scene. No verification involved.

Alternately I am starting to suspect there is a functional difference between the raw image that might be archived for burning to an eeprom - 'xepal.128' say - and a ROM image that Altirra or another emulator can directly utilize.
No difference - the BASIC XE image from FULS' collection above is a raw ROM dump. It's just that in the days before the Internet people really didn't know better and sometimes dumped their cartridges incorrectly, for example using wrong mapping or wrong order of banks, and then didn't verify the results. For example, the BASIC XE image hosted here at AtariAge has banks in incorrect order, which renders it unusable for emulators and EPROM burning alike.

Is there a utility somewhere than can scan the cartridge image and determine its format?
Not yet. I'm not sure it's possible to write such a tool without having to compare an image against a known list of images at some point.

In the thread linked earlier, one of my last posts contains a list of all known Atari cartridges, together with their mappings and CRC32 checksums. You can verify your images against it.

BASIC XE is OSS M091 mapping. Some images of OSS cartridges available on the Net are broken. Get the correct one from here.
