I hope that it's the history xml I noticed is wrong on these games as it says this but could be the description instead on MAME.
- SERIES -
1. Last Fortress - Paitoride (1993) 2. Paitoride II (1994) 3. Paitoride II - Adauchi Gaiden (1994) 4. Daitoride (1996)
Sorry if posted in wrong place but scrolling down it says history then it lists whats above.
They should be this if the rom description is right
