Download the U1MB firmware and attach 'U1MBS3.ROM' as the Ultimate 1MB firmware, and download the SIDE3 firmware and attach 'SIDE3.ROM' as the SIDE3 firmware. Providing both U1MB and SIDE3 are enabled in the emulator, it should then work as expected.
Dzięki. Jeszcze jedno, mam nadzieję ostatnie pytanie do szczęścia. Jak poprawnie skonfigurować nosnik danych dla SIDE3. Mam problem z folderami. Loader ich nie widzi. Pliki tak foldery nie. ATR działa. PS. Stosuję najnowsze romy z poleconej strony. Enable Ultimate1MB włączone.
Thanks. One more thing, I hope the last question for happiness. How to configure the storage medium correctly for SIDE3. I have a problem with folders. The loader can't see them. Files yes folders do not. ATR works. PS. I use the latest roms from the recommended site. Enable Ultimate1MB enabled.
Don't attach a virtual FAT filesystem. Attach a VHD ('Hard disk'). Altirra's virtual FAT volumes don't support folders, therefore you don't see any. Make a VHD using Windows' disk management console, format it FAT, put files and folders on it, attach it instead of the virtual filesystem and off you go.
