Well I’m stumped

V1.0. XboxHD+ and OpenXenium from AliExpress.

XboxHD+ board is flashed with Team Resurgent’s HD firmware.

OpenXenium is flashed with PrometheOS 1.5.0

128mb RAM upgrade with RAM taken from a donor 1.0.

Full console recap with Console5 kit (except the power supply)

TSOP is flashed with Cerbios 2.3.2. The BIOS on the modchip is Cerbios 3.1.0.

PrometheOS constantly freezes. Sometimes I get a few seconds in the OS to navigate. Sometimes in freezes instantly. I’ve reflowed the pin header many times. I reflated to XeniumOS and it works perfectly fine with no freezes.

I get some minor artifacting when booting into Cerbios. I also get some screen flickering on initial boot in PrometheOS and UnleashX. I checked all the chip legs for bridges and continuity. They’re good, clean and connected. So then I thought maybe it’s the caps. I replaced all of the caps on the motherboard. I messed up and lifted a pad for a SMD cap. The pads were still connected to their traces so I reinforced them with some copper strands. Continuity is good and cap is soldered firmly.
