I saw earlier in this thread that someone thought it would be nice to have physical buttons to select/load their custom presets. As a side thing I wanted to work on, I decided to give it a try. This edit is
kinda messy, but through testing, I haven't noticed hiccups to the actual use of the device during gameplay. OLEDs can now be used to display which preset is being selected/loaded, boot-up messages, and various GBS data (resolution, input, etc.).
No idea if this would actually be useful, but if this sounds like something interesting, I can send around the edit. I already have a to-do list for this, but perhaps some others have good feedback for the functionality or aesthetics. The hardware needed to actually use this is straightforward, consisting of three components: SSD1306 128x64 I2C OLED and two toggle push buttons.
Some other things to note:
- SCART, VGA and Component were used to test (PS1,Dreamcast and PS2)
- I opted to use this particular OLED due to size, cost and availability. Could change in the future to use LCD screens or perhaps both that way users have an option on what they want to use.
- Different configs of this OLED don't matter, like color. Just make sure the size and comm. method is the same
- I'm still working on this so expect weird or unusual things, particularly the OLED functionality.
When taking this photo no input was connected hence the bypass and interesting refresh rate, after some time it will blink "No Signal"
Here's a some example photos:
EDIT: I've now completed this edit to a usable state and soldered to a protoboard in the mean-time. There is some minor issues software-wise, but that will fix be shortly. Here's some crappy pictures to illustrate an example of a GBS 8200 with an OLED. Using a PS1 via SCART. I forgot to picture this, but you can might able to see the two buttons that control the loading/selecting of the presets.
Do you have any updates on this? a guide to build it etc? I would love to make something like that.
