"windale" reported this problem on spectacol bug tracker: https://github.com/bog-dan-ro/spectacol/issues/25

I tried booting SCL files but it sent me to the TRDOS prompt. I manually LISTed the contents and loaded the bootable file (LOAD"filename") but it just said DISK ERROR.
SCL files and possibly other Russian clones dont work properly.
When you finally get them working can you make them autoboot (like Unreal Speccy Portable does). Thanks.
