[Coco] Do all undocumented features of Coco3 (ex. S-24 mode) exist on emulators like CocoFPGA?

[L. Curtis Boyle]

Yes, using the LPR setting on the GIME (# of scanlines per pixel), you can simulate SG24, SG12, etc. but it it does not do text characters, as mentioned.

This is an undocumented Coco3 feature. The emulation of S24 is partial as text is not available in an S24 picture.
