The ElkSD64 has proved to be extremely popular, but people regularly asked if there was a version that would work with the Plus 1 expansion. Now there is. The ElkSD-Plus 1 is a combined SD card interface and RAM expansion in cartridge form, which works in a Plus 1 cartridge slot.
It's not just an ElkSD64 squished into a cartridge case, it actually boasts a couple of new features.
The ElkSD-Plus 1 is cable of using two seperate versions of the MMFS filesystem, switchable either by jumper or in software. By default MMFS 1.4x is used, ensuring maximum compatibility and stability. But MMFS 2 is also available, which some people will prefer as it enables easier use of .SSD images but at the cost of breaking compatibility with game launcher menus.
Another new feature is the failed flash recovery system. If a problem occurs when updating the ElkSD-Plus 1's software setting a jumper will enable the cartridge to boot from a backup copy of MMFS and be able to re-run the update flashing process.
The Plus 1 cartridge slots are limited to two 16K memory banks per cart, as one bank is used by MMFS this means the 32K of RAM on the ElkSD64 has had to be reduced to 16K on the ElkSD-Plus 1.
The ElkSD-Plus 1 cartridge is now shipping in limited volume.
