This glitch was found by 100% accident in this year... And by testing what'll happen if run in to the save point as Richter
(The Richter run+save freeze glitch itself seems to be old, but there happened to be something new in DXC version!)
1. Enter the save point at the top of Royal Chapel as Richter
2. Stand on the red floor under the "ball", face left, then perform "→→+↑"
3. If Richter returns to the position with high speed (as fast as he runs), there are dusts on the ground and the "save question box" opened, mark this as a "successful move"
4. Perform the "successful move" about 10~20 times then exit the save room. You'll see Richter warped to the next room and immediately falls to the bottom of the screen
5. Then you can explore white maps just like when Alucard goes OoB! WOOOO-HOOOOOO!
It seems that Richter can't get through this position... And it seems that Richter can't perform a skill/item/item crash that
pauses the screen, so he can't dig more white maps at the border of the room
But at least the Royal Chapel spike room ... It's not a dream!
Only works on Dracula X Chronicles (DXC) version
This glitch actually
creates a shift line in the single tiny little piece of
save room!
This glitch can be used in other save rooms, but there seems to be no useful results
In PS JP V1.0 version Richter sucks in the middle line of the room and can neither save nor escape, so it can't be performed on PS versions
