Glad to help you! I'm not good in documenting my software, and that is why i linked  project to here for all info i missed in github!

I wrote an RTO User Manual (sorry, right now only in Italian) based on my tests and checks directly with the RTO.

As the Intellivision I own do not show the RTO "Splash screen" when is turned on, the manual reports the procedure to activate the RTO based on this behaviour.

I do not know if the RTO currently is performing the "Auto - Reset" of the console.

If there is any interest I can do an English version of it.

You could try to rename the file, it may be too long and sw doesn't find the ".bin" as suffix and discard it.

Also, remind to put in the same folder the .cfg with same name if needed. And, 0.cfg file (the default mapping) must be placed always in root folder

My Roms used for tests are ok with all items you reported, filename, extension, .cfg file etc.;  The issue was that I kept the .BIN with the .CFG into a folder with the same name of the Rom, instead to put them directly into the, i.e. "A" folder.     So, the issue has been fixed 😀

Also it's possible to create any name folders for grouping and sorting the Roms, that's perfect 👍

Thank you for your help and sorry to have bothered you off with a stupid question.

Hi RKOTower, happy you successfully made the RTO, and i love the case with golden remarks, i must buy a gold uniposca! 😝

About the folder handling, i used sdfat library that doesn't support "previous directory" command, so i implemented a simple code for handling ONLY ONE subdirectory level (i use the directory 0-9, A, B, C etc. for grouping and sorting roms).

Further sub level may be added, but i had no time neither motivation for working on it.

 

Hi Andrea, thank you for your replay and clear explanation.

Your code to put the Rom folders into one subdirectory level it's a very good solution; I did it, but I got the same behaviour, when going inside the Rom folder the display show only the two dots and Kb.0. but not the Rom name. (see picture below)

I put the Rom folder inside a folder named "A" and I did the test using an SD formatted in FAT and one in FAT32 but same result.

Did I use the right procedure ?

i can agree...

only to add that cost of RTO depends in great part by the Teensy 4.1, i bought a couple from the productor in USA so i paid them 27$ each one, but prices are very different around the world and market. On ebay someone started selling the empty PCB for RTO too, but it's cheaper buy 5 of them from china (about 10$ all them). So, total price for a "power user" may be under 60$, and it's not so difficult to assemble it. Of course, if you are not able to solder an IC and you have to pay someone for doing, you could "turn" to Backbit, it's a great piece of hardware, i like it and maybe one day i'll buy one (i didn't realize it's again available!).

About compatibility, i think RTO and Backbit are quite the same (and i didn't found any rom bigger than "The big apple" until now, but never say never... ), and some feature LTO has, like encryption or new instructions, won't be implemented in no multicart since they are a LTO "encrypted" solution!

Hello Andrea, first of all thanks a lot for your amazing project, and "Chapeau" to put your great job available for all.

I did two RTO (below picture) and they are perfectly running, I did many tests and checks with excellent results.

I have a question about the possibility to put the Roms into folders; currently the Roms must be placed in the the root of the SD, is it possible to modify the software to place them inside a folder ?

I.e. : the Rom "Burgertime" inside a folder name "Arcade"  "Arcade/Burgertime"
