Description
Installation instructions: https://github.com/borti4938/SNES_MultiRegion_with_DeJitter_QID
Please note: If you’re installing this kit with dejitter enabled alongside an RGB mod, you will need to change some resistor values on the RGB board. For the Tzorrimahm RGB kits we stock, please check the BOM page for correct values by clicking here. If you order both kits from us, we will include the two resistors for you by default.
The kit is sold as DIY, please make sure you are confident in installing before purchasing.
SuperCIC
Hold down the reset button in order to swipe through 50Hz (green LED), 60Hz (red LED) or Auto-Region (yellow LED).
With the SD2SNES you are able to pair the SuperCIC with the flash card. Then you’ll be able to switch between 60Hz and 50Hz mode. However, you need to have the uIGR, which is master for the region setting, in SuperCIC pass through mode. Some more information is given below.
uIGR
The uIGR sniffs the controller inputs directly at the controller port. Therefor it is able to detect certain button combinations. All button combinations are collected in an overview PDF, which is available in German and English. Here are the most important ones:
Region forcing:
60Hz: L + R + Select + A
50Hz: L + R + Select + Y
Auto: L + R + Select + B
S-CIC pass through: L + R + Select + D-pad left OR L + R + Select + D-pad right
Reset:
simple reset: L + R + Select + Start
double reset (back to main menu of sd2snes): L + R + Select + X
Region Patch
Overwrites region if game request register $213F, where bit 4 represents the region. Region patching can be disabled (see uIGR PDFs). You also have to consider switching off the region patch if using non-original cartridges or flash cards (sd2snes with Pairmode with SuperCIC is not a problem).
DeJitter
In NTSC mode the SNES outputs a shorter scanline in non-visible area. This might be an issue for certain TVs if you use pure analog to digital conversion without frame buffer like the OSSC does. DeJitter ‘removes’ this shorter line by pausing the clock for a few cycles.
As drawback this mechanic varies output timing a bit, however the inaccuracy is neglectable when comparing it to clock variations throughout different consoles.
At the moment, DeJitter is enabled by default and can only be disabled by setting jumper SJ31.
DFO
Short for dual frequency oscillator. Actually in combination with the CPLD this allows to switch between three output clocks plus two colour carrier clocks. If modding board is correctly installed, there is nothing special to consider here.
