Sega Saturn Side Rooms Underfloor

How can i get these rooms marked in red, i tried to use the wingsmash and up trick like in ps1 but i can't get them

Transformations on saturn emulator are slower than on real console. Some rooms are harder to grab when playing on emulator.

Try this:

1-Transform into wolf then revert to Alucard (now you have one jump available);
2-Jump toward to the right side then do a DHR chain while holding the [right] button.

Must work.
