AMIGA 500 OCS Version 1 Alpha 3

1. HDMI: Support for interlaced video modes: Demos like Batman Rises (2022) and Second Nature (2026) flickered heavily in Alpha 2 as we treated the two interlaced field as frames and not as fields.

2. "VGA" aka "Analog" video: The core now offers an own menu where you can configure your analog video out. Interlaced modes are supported when you use the authentic 15 kHz modes. This help page from the C64 core explains you more about this: https://github.com/MJoergen/C64MEGA65/blob/master/doc/retrotubes.md

3. Support for active mouse adaptor such as mouSTer and MicroTom: Right and middle mouse buttons (should) work now.

The core is not self-explanatory. Please read the README.md here: https://github.com/sy2002/AExp/blob/develop/README.md

As this is an Alpha release, it is not released on the FileHost, but only here in this Discord channel.

🇺🇸️🎆️ Join me tomorrow at 2 pm (Eastern) as I continue America's 250th Fourth of July celebration by breaking out my MEGA65 to create 8-bit fireworks. I also demo the new <#1313409877393276948>! You won't want to miss it. The chat will be on fire!

AMIGA 500 OCS Version 1 Alpha 4

Writable ADF floppy support: Save game states, really "work" with your AMIGA, format disks, etc. The core cannot CREATE .adf disk images, but it can write to existing .adfimages on your SD card.

Please test thoroughly. What I tested: Renamed an icon in the workbench. Power-cycled the machine. Worked. Using the CLI's Ed editor, I changed my S:Startup-Sequence which hardcoded a NORWEGIAN keyboard mapping for my Workbench to the U.S. mapping which is closer (but not identical) to the MEGA65's keycaps. Then I rebooted and it remembered my settings. (BTW: If this "how to do a keyboard locale setting is in workbench valuable for anybody - see screenshot). I also pressure tested the writing by changing stuff while it was still storing to the SD card. Everything seems to work very well.

This thing is as safe as the C64 core's writing mechanism. This means: It is an Alpha version - yes. But it won't bork your SD card. The worst worst case (which I consider very unlikely) is that it might corrupt the currently mounted .adf file. But we will only find out if you guys are now testing it: Save game states, draw images with Deluxe Paint and save them, work with your favorite coding IDE and save and compile code, etc. etc. Please report back in the <#1313409877393276948> channel if this thing works as expected.

There was a lot of Mouse Confusion(tm). I documented everything neatly. Please read before you ask this stuff again 🙂 And in general the core is not self-explanatory, so the README is your friend: https://github.com/sy2002/AExp/blob/develop/README.md
