First public release for FS-UAE Amiga Themes!

I needed a little pause from the Mega Bezel, so I decided to give the finishing touches on the Amiga 1200 Synthwave theme for FS-UAE. I know this is not RetroArch related, but this is a really nice showcase of what we the dynamic overlays we may be able to do with LED and data devices interactivity.

MULTI-FLOPPY DATA SIMULATOR (DFx)

The 'data-simulator' adaptor on the left side is equipped with a dot matrix display showing status from DF0, DF1, DF2 and DF3 in real-time, meaning you get LOTS of information about disk activity. 'Data-Simulator' UX is based off IRL Gotek adaptors, hence the codification of disk access and the track count.

On the left: DF0 read access (RA) and track cylinder in real-time

• DISK PRESENCE SWITCHES a row of on-off switches indicates that the floppy unit contains media. If you eject volumes via the FS-UAE menu, you will see the switches toggling position
• DISK TRACK DISPLAY shows the cylinder currently being read. Empty floppy units will show dashes in place of cylinders number
• DISK ACCESS NOTIFICATIONS shows the Read Access (RA) and Write Access (WA) for each floppy unit

LED INDICATORS (ODD, HDD, POWER)

LED indicators on the right side give a real-time glimpse of data units and power activity via classic Amiga blinking LEDs.

On the Right: HDD & POWER activity

• HARD DISK (HDD) LED shows reading/writing activity for all of the hard disk units via a blinking LED
• OPTICAL DISK (ODD) LED shows reading activity for all of the optical disk units via a blinking LED
• POWER LED shows energy supply status via an on/off LED. Some applications shut the LED off in run-time

AUDIO INDICATOR (HEADPHONES)

Audio indicator is included on the upper part of the 'data-simulator' adaptor on the left side. It's shaped like an headphone and shows three different audio output statuses based on colored lightning.

• NO LIGHT means audio is off, blue light means audio is on
• YELLOW LIGHT means you're playing an audio CD
• RED LIGHT means something is not working correctly (ex. empty audio buffer)

POSTPROCESSING & FX

This graphic theme leverages on a mix of FS-UAE rendering effects to achieve a nice retro-feeling. Old displays were not as pixel-perfect and sharp as nowadays LCD/OLED panels, so old graphics assets may benefit from some postprocessing at the expense of minimum CPU/GPU calculation power.

Default theme.conf file includes:

scanlines = 1
scanlines_dark = 6
scanlines_light = 3
shader = curvature
fsaa = 4
texture_filter = nearest

THEME SCALING AND POSITIONING

This graphic theme is hard-coded and tested for 1920x1080 Full HD standard resolution. Amiga content is preset to specific display rectangle values corresponding to the graphic overlay transparency.

This way I can achieve nice visual results with zero configuration, nonetheless this may introduce some negligible overscan and aspect ratio inaccuracies, because of the curvature shader and different PAL/NTSC output standards.
