I've come up with a system to make Super IRG 2 font pics.
You will of course need Tebe's G2F to do this, and a good photo editor like Photoshop.
The limitations are of course that the pic will need to be narrow mode, and you can only display 16 lines of character.
First, load your pic into photoshop and resize it to 256 pixels wide, and also optionally to 128 pixels high if you want the entire image to fit the display. Save it
Load your saved pic into G2F, and when the window pops open on the bottom, tick "5th colors", "Dither 2x2" and "Sort Colors". Make sure the pic is in narrow mode (32 byte).
You get a listing of colors you can choose from, along with 708 through 712 ... select 5 colors from this list, 712 being your background.
Set your character set usage to "Standard", then edit char set. Go through the first 4 character sets and save them.
Go to edit colors and make a note of the color settings, I think you can also save the .COL file too. Save your G2F, then export a .SCR file
Reload your picture file and repeat these steps, except choose different colors (keep 712 the same). Again save font files, SCR file, G2F, color settings.
Attached is an ATR of a Space Ace pic I did. The program SPACEACE.TUR is a program which will open up the font files and the SCR file and display your picture. When using SCR files, its a matter of choosing which SCR file looks better. Sometimes you get nasty artifacting because of PF2-PF3 inverse conflicts.
Lines 1020-1027 load the font files into memory. Lines 1190-1201 are for color settings and character set pointers. Lines 2000-2010 load the SCR picture file.
How this works is you get an Antic 4 screen, and the program uses a combination VBI and DLI. The DLI changes the character set (CHBAS) every 4 character lines, and the VBI flips CHBAS, the DLI CHBAS pointers, and color registers 708-711 every VBI to simulate 23 colors. Due to limitations you can only get 16 character lines onscreen. This could be increased if some kind of algorithm to optimise character usage could be written. Reducing your color resolution by only flipping 3 color registers will increase your character display by 4 lines as well.
This is the original picture

I can do the converter. If anyone has a format description for me I will do it. I can´t do the player because I have no IDE-Interface. I have Sio2SD in my XL and Altirra.
They look sufficiently detailed and colourful for video transcoding. I'd love to see some full-screen colour vids running off IDE Plus 2.0 at 10fps!

ZIP files are allowed so just rename you rar file 'filename.rar.zip' and then downloader can change erase the zip extention and use the orignal rar file archive.
I made a setup, but I´m not sure if it works for you. It needs .Net 4.0 and some Devexpress-Libs. Could anyone try this out please?
Unfortunately i am not allowed to attach a rar with a setup. I can understand that.
Send me a message if you are interested.

I must admit I haven't read up on the mode's design so my suggestion wasn't really informed. However, throughput is in the 64KB/s region, so we'd be looking at more like 5fps. One way or another, it would be an interesting challenge. I guess it could be tested on SIO equipment and run full-pelt on the IDE setup. What about if the vertical resolution was halved (or is that not possible... or even desirable?).
