Kung Fu Flash 2 vs. SideKick64: Which Is the Better C64 Expansion?

243

Arctic Retro takes a closer look at the new Kung Fu Flash 2, a follow-up to the popular cartridge solution for the Commodore 64. The updated version introduces built-in 1MB RAM Expansion Unit (REU) support, but how does it compare to the SideKick64, another advanced storage and memory solution?

What’s New with Kung Fu Flash 2?

Kung Fu Flash 2 continues to offer broad compatibility with cartridge types, PRG files, and D64 disk images. Users can load these files by placing them on a FAT-formatted microSD card and selecting them through the built-in launcher. The major addition to this version is its ability to emulate a 1MB REU while simultaneously handling disk drive emulation.

The REU function activates under specific conditions:

  • When executing a program using the default option (RETURN)
  • When mounting a disk image or directory through the file options menu (SHIFT+RETURN)
  • When launching BASIC via F6 (C128) or F7 (C64)

However, the REU is disabled when emulating cartridges (CRT files), meaning users must decide between expanded memory and cartridge functionality.

SideKick64: A More Versatile Alternative?

SideKick64 provides a broader range of features by utilizing a Raspberry Pi 3A+, 3B+, or Zero 2 (C64/C128/VIC20 only). It supports not just storage solutions but also memory expansions, sound devices, freezer cartridges, and kernal replacements. Users can combine multiple functions, such as running a kernal replacement alongside freezers or a GeoRAM expansion.

Supported file formats include PRG, D64, SID, MOD, YM, and WAV. Additionally, built-in tools like Disk2EasyFlash and PSID64 make it a comprehensive solution for users looking to expand their Commodore experience beyond basic storage.

Choosing Between the Two

For users seeking a simple, efficient storage and cartridge solution with added REU support, Kung Fu Flash 2 remains a solid choice. Those looking for a more feature-rich expansion, including advanced sound options and broader emulation capabilities, may find the SideKick64 to be the better fit. Each option brings something unique, depending on whether the priority is straightforward usability or extensive customization.
