does anyone have a broken DSi or 3DS, or a Wii Fit U Meter they'd be willing to donate? or just anything that has a 78k0, 78K0R or RL78 chip

"broken" being the screen hinge broke, a badly corrupted flash, etc, it still kinda needs to boot

context: I'm trying to get the firmware out of the DSi BPTWL chip and maybe also the 3DS MCU, and also the fit meter because why not, as these are very similar chips. except they all differ in small ways in their in-circuit flashing interface and bootrom (which implements the former) so that I need to sample a number of them. also the RL78 debug interface has been semidocumented by fail0verflow and I want to try to expand that to the other chip types. access to this debug interface, even when disabled by the firmware, would make it much easier to recover the flash using voltage glitching (lower complexity exploit)

yes I know the 3DS MCU firmware has been obtained already but that chip is in the middle between the 78k0 and RL78, making it useful
