I do not offer this install service since doens't require soldering skills but I recommend this mod.
You can purchase GDEMU at the official site for 130 €: Purchase official GDEMU
Or get a clone for around 50 € on ebay, as far as I know there is not major difference apparently you need a official one in order to have firmware updates, adn I guess that the clone material quality is a little worse.
DCdigital install service form:
Its not impossible but kinda hard to find the DCdigital of black dog
If you can't find it I recommend to try the DChdmi from kaicolabs: Dchdmi kaico.
