Finally got the Tinytendo to work after a year.
To narrow down the troubleshooting, I soldered the untrimmed CPU and PPU with wires. Finally a sign of life after soldering the additional 3V line on the driver board. Unfortunately it is not in the wire diagram.
1st trimming attempt with PAL chips was unsuccessful because they cannot be trimmed small enough.
2nd attempt, from now on with NTSC chips.
Worked well until I started sanding it by hand, unfortunately the circuit tracks fell off shortly before the end.
3rd attempt, first partial success, one chip completely defective, but with the other Super Mario Bros starts after a reset. But unfortunately without Mario.
4th attempt
When grinding the chips, this time I made sure to grind them extra convexly so that the metal protection was still there. Luckily, the grinding stations in the shop made the work a little easier. After positioning the chips on the board and using good flux, the soldering went very well.
Attempt was finally successful.
Console starts
5 tlrom and 5 nrom games complete the project.
Thanks to redherring32 for these cool but very difficult project.
