Technical Frequently Asked Questions (FAQ)

Before writing to us, check here

My ZX Spectrum gets stuck on the stripe screen when loading .TAP, what do I check?

Verify the power source and voltage lines first. Then check the dump with the official MD5 checksum and discard non-FAT32 microSD cards.

Does Multiply Pro work on my Amstrad CPC?

No. Multiply Pro is designed and verified physically on the Sinclair ZX Spectrum 16K/48K/128K/+2/+3 and Harlequin clones. For CPC, we use CPC Elite+ and CPC Mini Dual.

Can I update the firmware without losing the warranty?

Si, the firmware is open-source and the update is free. We publish step-by-step guides and the .UF2 binary with a validated checksum in the Firmware section.

Do you need replacement parts (ULA, memory chip, connectors)?

Si, as replacements for repairs listed in the store and under request for third-party rolls with B2B partner program.
