Included SSD ran hot during sustained stress
Robtech found the included 1TB eKit Store SSD reached thermal-throttling territory when he stressed the CPU and SSD together for an extended period. This concern applies to his drive and test conditions; it is not a normalized temperature result.

Batocera 43 connected to Wi-Fi and Bluetooth
Team Pandory booted Batocera 43 from USB and reported working Wi-Fi and an 8BitDo Pro 3 Bluetooth controller on his 16GB/512GB unit. This is a basic compatibility check for that configuration.
