Add a 12V rail for the N64 slot. This is not currently implemented, but as the six-slot adapter is the hardest of the 2 boards to upgrade having it now will save some effort for anyone wanting it in the future. It also makes it easier to externally supply 12V by attaching clips to the 12V and GND header pins.
Also improved the silkscreen a bit to match the main PCB.
Unable to actually test this myself because I do not have a HW3 to test on. However, looking at the schematic, if the EEP switch is set to the off position then the pin will be floating and the result of the 1K resistor test will be random.
Added :
Treasure Hunter (Rev1)
Assembloids (Unl)
Removed :
4 in 1 - Hash block / Challenger Tank / Brain Power / Jacky Lucky (hash was obtained from a rebuilded rom, impossible to get with the OSCR)
DS1307 does not seem to have the lost lostPower function. So the time does not get set on upload and needs to be set manually as described in the [wiki](https://github.com/sanni/cartreader/wiki/Real%E2%80%90Time-Clock#setting-the-time).
In Config.h set like this:
````
#define RTC_installed
//#define DS3231
#define DS1307
````
Connect "Tiny RTC I2C module" or similar to the SDA/SCL/VCC/GND pins.
* Migrated files to KiCad 7
* Added RTC
* IC: Analog Devices Inc. DS3231MZ
* Battery holder (CR1616): Keystone Electronics 3012
* Cleaned up traces
* Changed ground fill to solid
* Removed test pads and LCD solder jumper
* Cleaned up/prettified silkscreen and logo
* Cleaned up some footprints (more to come eventually)
* Added 3D models for board display
* Schematic image is now a PDF since it has 2 pages
The `setVoltage()` function should be called even when `ENABLE_VSELECT` is disabled because `ENABLE_3V3FIX` also uses it. There is no resource cost to do this as when both options are disabled the compiler will optimize this function out. This just "future proofs" the code so if that function ever does more it doesn't need updated everywhere. This applies to `setup_FlashVoltage()` as well.
The changes to OSCR.cpp are just for code formatting and additional comments to clarify this.
