I went out and bought a SanDisk micro SD card, the smallest memory I could find was a 32g

 

I tried pressing the aspect button and the back of the console but it did not adjust the size.

 

And my bad I miss understood the number of games.  On the picture of the menu screen, top right corner, it reads 48 items found.  I thought that meant number of games, but I counted it and I count 28 games which makes more sense because I do see when I press Direct download it says I'm downloading 13.2 when the size of the file 13.15.  The .13 must be the missing 5 games.

 

Maybe its a matter repeated attempts of downloading?

Once the firmware has been upgraded to the community build, the aspect button does not serve the same function as with the original Hyperkin firmware.

 

Can you take a picture of your screen at the Stella launcher and share it with us?  I'm just not sure what you are downloading or what you expect.

 

If I had to guess, the 13.2 size is probably just 13.15 rounded up or otherwise calculated differently, in other words they are likely the same.

Just upgraded the community firmware to 6.3 and what I see in Stella is 6.1_rc1. What is that?

Ups. That sounds like I built from an old tag. *slaps himself around a bit with a large trout* . I'll pull the binaries and do a new build.

Would it be possible to use this or modified image on some Allwinner H3 SBC like Orange Pi? I would like to use my Orange Pi in Flashback X case and to have the same Stella only environment.

Sounds feasible (@DirtyHairy should know better), but the Stella team has not the capacity to support multiple platforms. So you would have to do the necessary modifications yourself.

Yes, I think this is feasible, but you'll have to do some modifications. The R77 firmware is based on an old version of the Orange Pi uboot and kernel trees. The hardware is stripped down, though, and I am not sure whether there are any changes from hyperkin to the device tree. To my knowledge, the only things R77-specific are the dumper (which communcates with a MCU over tty) and a kernel driver that handles joysticks and hardware buttons (using GPIO and i2c).

At a minimum, you'll have to remove the dumper from the init script and start Stella directly, and disabling the Hyperkin kernel driver is a good idea, too. Additional changes may be required in case there are more hardware differences, and you may have to reenable more OrangePI stuff in the kernel config. Provided some experience with (embedded) linux, I think it can be pulled off. I don't have time to do any actual works on this, but I'll be happy to give you advice ;)

I'm afraid we have found a few issues with Stella 6.3 that particularly affect the R77. Notably, savekey-enabled and CDF cartridges fail to work, and the dumper does not work correctly (aka 6.3 won't play real cartridges). In addition, the dumper may send Stella into a kill-restart loop. I've removed the build to keep everybody from finding out the hard way ;) There'll be an updated R77 build soon.

Is anyone noticing issues with H.E.R.O on 6.2.1? There appear to be some frame drops for me - if I disable the TV effects it runs fine..?

Do the frame drops appear when the R77 is cold, or only after some time? How about other games, are they also affected?

How much RAM is in the R77?  The last CartCDF update increased the array size of myImage from 32K to 512K for CDFJ+.

From cold - haven't noticed in any other games yet (I only got the R77 today :)

That's pretty odd. Normal games without ARM support should work without any problems. 

Please let us know how other games behave.

will homebrew cartridges work on Retron 77 with community build image? (the actual cartridges, not ROM files).

 

or does it depend on the game? Let’s say I buy the newest release from Atari Age store, would I be able to simply plug the cartridge in and play?

This has been answered multiple times before in this forum. Please do some research.

so yes or no?

 

 

;) no, but seriously I didn’t find the answer. There seems to be page after page about people having issues with particular controllers. I know the homebrew carts will not work on the standard Retron 77 off the shelf, so my bet would be that they still won’t work on the community build, but I thought that someone may reassure me. Funnily enough I was thinking of buying Aardvark! Is it similar to the Stella releases, that changes are implemented regularly to increase capability with new roms, or is that not possible with community build for Retron77?

And this cannot be improved, because the R77 cannot provide the cartridge data (ROM) to Stella.

thanks, kinda dissapointing 😕

Yes, especially because it would have required only a bit of extra work to make the dumper better. Or at least allow to update it.

 

Anyway, IMO the slot is only a marketing gimmick.
