Tjoppen Posted September 27, 2011 Share Posted September 27, 2011 Using the latest eeloader (eeloader_104e_PAL50.bin) and BIOS (hbios_105_PAL50.bin): When I program the Harmony with a 128 B ROM everything works as expected. If I instead use the menu loader (BIOS) I get various weird results (the console typically displays a black screen with gray bands). If I enlarge the ROM to 4k by simply concatenating 32 copies of it then it works fine. My guess is the BIOS simply doesn't mirror the ROM across the adress space properly. For the curious, the ROM in question is an experiment in generative "music", via this thread on pouet Quote Link to comment Share on other sites More sharing options...
cd-w Posted September 29, 2011 Share Posted September 29, 2011 Yup - this is a known-limitation of the Harmony. There isn't enough space for the code to expand out the ROM image, so you must do it yourself before uploading to the Harmony. Quote Link to comment Share on other sites More sharing options...
Tjoppen Posted September 29, 2011 Author Share Posted September 29, 2011 That sounds like a challenge On a related matter: Stella seems to have a similar issue with ROMs <= 32 B. I noticed that pretty quickly when messing around with 16 B stuff.. Quote Link to comment Share on other sites More sharing options...

Do you have any 4K .bin to share that you got working on the 2600? Quote Link to comment Share on other sites More sharing options...
