No issue. PC CHIPS G3101 / Paradise PEGA1A EGA card (AUTO MODE HEGA) profiles. #308

Hello, I share here the profiles of the EGA card "AUTO MODE HEGA". It is a card with the PC CHIPS G3101 chip.

It is possible that they can be used in the Amstrad PC1640 and other Paradise PEGA1A chip cards, since it appears to be the same chip with a different name. In fact, I've used the Amstrad PC1640's DISPLAY.COM utility (once patched so it doesn't look for the "AMSTRAD" string in the BIOS) to configure the various monitors/modes on my card.

There are many profiles for the Hercules graphics mode, as I have tested several programs with native support, as well as several CGA emulators.

Sorry if this is not the right place to put it.

@grxt Thanks, I'll add it to a future release What software is generating so many different Hercules timings?

Ok, thanks!

I have used native Hercules graphics modes with: Windows 3.0, Psion Chess, Korean Dungeon Boy, GhostBusters II, MiniPutt, ...

In the CGA emulation modes (which is where so many timings are generated), I have used among others the emulators that can be found on the page https://www.vogons.org/viewtopic.php?f=61&t=61035&start=160
