Finally the newest hardware release for the CPC is there: The MegaFlash. It is a ROM box, created by Bryce, which contains 512KB flash memory, which means that you can program it directly with your CPC. It is similar to the ROM-RAM-Box by the Inicrons, the RAM-Card by RAM7 or the SYMBiFACE II by Dr.Zed (only the ROM part). You can now store ROM software like the Starkos tracker, Maxam, Protext, etc. in it.
If you want to order such a device, be quick (only a few devices are left) and send Bryce a personal message in the CPC Wiki forum.
[UPDATE:] Sorry, I totally forgot to write about the software you need to program the MegaFlash ROM box. The box can be programmed with the MegaFlashROManager by TFM which is available for Basic and FutureOS. Thanks for your comment, TFM!
