So here is the release of the RetroN 77 Community Build Image. This is a firmware replacement image for the RetroN 77 intended to be written (using an appropriate tool, not included) to a microSD card to be used with the Retron 77.
What it does do:
Brings a rather large quality of life update to users of the Retron 77, especially those that intend to run roms from the microSD card.
What it does not do:
Fix any existing controller, dumping or compatibility issues (other than those fixed by bringing the version of Stella being used to 3.9.3)
What it looks like:
Where to get it:
Here If you are unfamiliar with Dropbox, look in the upper right corner for the Download dropdown, and select Direct Download to download the zip image package.
How to use it:
Read the included README.rtf - it contains important information you should know.
As mentioned the included image (sdcard.remo.20181120-1353CB.img) must be written (as an image) directly to your microSD card - this does not mean copy the image as a file to the card, it means use an imaging tool such as USB Image Tool or Win32 Disk Imager or Etcher
Caution is advised here, if you do not know what you are doing you may wind up wiping out your computers system (or other) drives. DO NOT DO THAT. Ask someone for help if you aren't sure what you are doing.
Once the image is appropriately on the microSD simply boot the RetroN 77 and you will immediately notice a difference. The RetroN 77 will no longer boot to the Hyperkin UI, but will boot directly to Stella.
A truly massive thanks to stephena for kindly lending me his time so that I was able to achieve my initial goals without inelegantly hacking into Stella itself, and then for taking even more time to make the wonderful Stella specific changes to the stella3-r77 branch for this build. What you see when you utilize this image simply would not have been possible without his talent and generosity. And of course this includes thanks to him as always for Stella itself : )
Thanks to Thomas Jentzsch for his testing, input, discussion and kindly giving permission to include his awesome titles in this distribution (yay!) , and to Atari Pixel for his work and for being a great partner in this project. Additional thanks to fellow AA members Sneakyturtleegg, gorfcadet, iesposta, ColecoJoe for image testing and feedback.
