I would like to change the emulator of choice from vice to Denise, is that possible from within ugBASIC?
Hi Skulltip, and thanks you again for the comment!
It looks to me like you've enabled the option to treat warnings as errors. If you disable that option, you can build without problems. To disable it, go to Build -> Options... and uncheck the Enable warnings (-W) checkbox.
Regarding the warning, it's a warning because, since ugBASIC is an integer BASIC, it uses 8-, 16-, or 32-bit data types. Therefore, it's possible that certain operations, such as multiplications, may exceed the size handled by that specific type, leading to representation errors. Of course, it's just a warning—usually these aren't problems that occur with normal use, but for some cases, it's important that this not even be the case, which is why the warning exists.
