Hello all, I'm new to this forum and new to understanding how electronics and mods work, thanks for your patience.
At the beginning of the pandemic I bought a modded GBA SP from an individual's online listing. It has a Funny Playing v2 screen kit. The 1st rechargeable battery in nintendo's intended battery compartment's replaced. Additionally, there's also 2 more batteries behind the screen. I understand the screen kit with an everdrive x5 mini is a hungry combo, so I am glad to have many batteries.
When I received the GBA and an everdrive separately, I played *lots* of Pokemon pinball advance. For years I played it often with no problem. I probably only put the GBA down for maybe 6 months at most before a few weeks ago I decided to try Mother 3.
Playing Mother 3, it started rebooting and once froze (still image, no input). Then I could restart mostly and continue playing. At first I thought it was the ROM. Until on one occasion it rebooted constantly so continued play was quite impossible. I realized the problem is getting worse.
Then I tried Pokemon Pinball again, but now the system always reboots as soon as I choose the table. I do not get to launch the ball. I couldn't hope to try play thru with interruptions as I do with Mother 3. I started to suspect a power draw issue.
With 3 batteries I ran the system with the GBA test cart ROM for 2:24 hours before it rebooted itself.
Then took out the 1st battery in the battery compartment, as it's easiest to remove. Without the 1st battery, I tested the SP with only 2 new batteries behind the screen.
With 2 batteries only, test ROM ran for 4:16 before shutting down instead of rebooting. This time I tracked the red light, which started shining solid at 2:11.
Then I recharged. With only 2 batteries behind the SP's screen, I was also able to complete an entire pokemon pinball game.
It seems stable without running the 1st battery. I am hoping if I replaced the 1st battery, this will solve the problem? If so, which battery should I choose? If not, what else could be the problem?
