OH YEAH! Thank you, Manuel! May code wasn't broken!!! With ASCII16KB mapper selected all works fine! Why OpenMSX can't autodetect it?

Because there don't exist ASCII16 ROMs of 64kB and smaller Smile So the Konami/ASCII mapper guessing only is done for sizes larger than 64kB.

What about the Sakhr Files rom? ASCII8 mapper and only 48kB!

There used to be an address range check but it was more annoying than it did good (as you found), so I removed it a while back. A recent development build of Glass can be gotten from here.

Can you indicate from which version was this done?

So what did it guess? You can see it by running this command in the console: toggle_infopanel

The guess system cannot be perfect... it's only a fallback for when the ROM is not in the database.

thegeps: you can help the heuristic by adding a few ld (nn),a instructions where nn is the value typical for the used mapper type. See https://github.com/openMSX/openMSX/blob/master/src/memory/Ro... for the full guess algorithm.

Sorry, toggle_info_panel (try toggle_in[TAB-key])
