The DLsite IDs for the first and second games are RJ196860/RJ345185
because the OP forgot to mention them in a place visible without login.
Although the game uses a custom/homemade engine, a translation is relatively easy since
GARbro can unpack its DXLib/DXArchive .wcd files (scenario text and pictures) and the game picks that.
I finished
translating the first game. Maybe I will translate the 2nd game later.
