Battery: CR1616 (should last 3-4 years). If you wish you can replace it with a larger battery (insulate it from the other components).
The maximum game size is 16MB as the way to access the EEPROM is to address higher than 16MB.
The PCB finish is ENIG.
This cart should work on every system that supports GBA carts – GBA, GBA SP, GB Micro, DS, DS Lite and the Game Boy Player. This cart uses 5-10mA more compared to a regular cart. If you would like us to test a game, check the Game saves tested list below.
Please note that the RTC chip appears to be sensitive to moisture levels of 70% or higher. If exposed to these environments for a few hours the RTC may stop ticking. So far we have only experienced this issue, no users have reported this.
How to calibrate the Solar sensor
In games that support solar sensor calibration (remember to save afterwards to keep the calibration):
– Indoors (at night): Hold it about 2 metres away from a light source so that the solar gauge will only activate when close to the light source
– Outdoors: Cover the solar sensor with your hand as normal
Only affecting orders before 1 Sep 2023: If you play in a very dark environment, you may have solar sensor issues.
EEPROM saving, Solar sensor and RTC in these games have been tested to work:
- Boktai (USA/Europe)
- Boktai 2 (USA/Europe)
- Boktai 3 (Japan)
- Boktai 3 (Japan with English translation hack, no solar patch required)
If your game isn’t here, send a quick email to firstname.lastname@example.org with the ROM file and ask us to test it.
