Makes sense. The memory handling in the SAM implementation is quite convoluted, so not that easy to add mirroring, will persevere.
There is no PAL CoCo2

That would explain that, then

I have no idea about this unfortunately. If you have an account at Mametesters https://mametesters.org it would be better posting the issue there so that other developers are aware of it, and someone with better DAC skills can take a look.
There is a version of MAME for Windows called MAMEUI which contains the menu bar "NewUI" (ditto for MESSUI from the same place) - perhaps this is the version Pernod70 is talking about.Azerpy wrote: ↑Wed Apr 24, 2019 2:52 pm Another question is about the facilities of use Mame. On the net, I see old pictures of Mess Windows, and on this forum you spoke two times of "menu bar" or "use new UI". Its seems for me not easy to change and load new files with keys scr lk, tab and these black and white windows.
So my question is "Is there in Mame a tool with menus I didn't find" ?
For machines to be shown as Available you must have an individual zip containing the required ROMs for that machine in your roms folder. You can easily check which ROMs are required by using the -listroms option from the commandline. So for Dragon 32 to be shown as Available you should have a dragon32.zip containing the following 2 files, similarly for Dragon 64 you should have a dragon64.zip containing 3 files.
Code: Select all
mame64 dragon32 -listroms
ROMs required for driver "dragon32".

The DOS is loaded as a cartridge, and Dragon DOS is inserted by default. To change the cartridge you need to enter the MAME UI, by first enabling the UI by pressing ScrollLock, and opening it with Tab. This is the internal MAME menu system. Select File Manager, then cartridge (cart), then [software list], then Dragon cartridges. You should see a list of all supported cartridges including dospls49 (DOSPlus v4.9B).
Not sure which posts of mine you're referring to without a reference. As others have mentioned you can use a front-end such as QMC2 if you want a Windows style launcher with menus.Azerpy wrote: ↑Wed Apr 24, 2019 2:52 pm Another question is about the facilities of use Mame.
