@arkh_zero c'est fait pour le titre 🙂
Sache aussi qu'en 7.3, ce n'est plus Hypseus mais Hypseus Singe qui apporte aussi des correctifs, possible que ça affecte ton cas 🙂
What version of rom do you have?
The reason I ask is there are versions that do that by design. The version I started with did exactly what you are describing, you just got random scenes and it never started with the draw bridge.
I went to the DLE 2.1 version and it starts with the drawbridge every time.
front he above webpage Rev A through F2 are the original rom sets. F2 is the rom set that has the 'Very Hard' setting.
