This APDU used to crash speculos. This is now fixed with b9d2cd3, 316dbdd and d3bdd45.

The app name and version were hardcoded (app and 1.33.7). df5a543 allows to set them through SPECULOS_APPNAME environment variable. For instance:

$ SPECULOS_APPNAME=blah:1.2.3.4 ./speculos.py ./apps/btc.elf &
$ echo 'b0 01 00 00 00' \
  | LEDGER_PROXY_ADDRESS=127.0.0.1 LEDGER_PROXY_PORT=9999 ledgerctl send - \
  | xxd -r -ps \
  | hd
00000000  01 04 62 6c 61 68 07 31  2e 32 2e 33 2e 34 01 00  |..blah.1.2.3.4..|
00000010  90 00                                             |..|
00000012

I'm not sure what the use case is, but if the environment variable isn't convenient, one can introduce yet another argument to speculos.py.
