Incompatible/unsupported apps:

Many app developers do not support this device anymore. You have three options:

Use previous versions of the app which were compatible with this device.

(APKMirror.com hosts many previous versions of apps.)

Try the incompatible app anyways. It may run under NEON emulation. Emulation is very slow. The ideal way is to use previous versions of the app which are compatible with this device.

Contact the app developer and ask them to maintain support for Tegra 2 devices.
