I recently got my hands on a digital copy of Illbleed final made by RGR, which is a Russian game company that is known for making illegal Russian translations of games from the Dreamcast and the Playstaiton.
Cases and discs look like this

The game plays exactly like the USA copy, but the only major difference is that there's some Russian text that RGR ended up putting in for the translation. However, the translation isn't exactly well done. So a lot of the game is still in English as well.
So passcodes with Woodpuppets is still 9663, the cashman vault one is still 1863, etc.
Trap patterns are still the same, and tricks all work the same with it.
Illbleed Final is best defined as a Bootleg Dreamcast release, and I would say would be just as viable as a regular USA copy.
