Dracula X (Akumajo Dracula X - Gekka no Yasoukyoku) 4Mb RAM Sega Saturn

wmarcio

I would like to share with you on the forum information about the game Dracula X from Sega Saturn. Recently, I read in a Chinese forum (I will not post links to the game) that the game was hacked, and that now we can use the 4mb ram cartridge to run the game, and the improvements are many ... I tested it in the retropie x64 with lubuntu 18.4.4 and works perfectly.
A test video:

PS. I hope I didn't break any forum rules, if I did, I apologize.

@barbudreadmon Original readme from creator:
I used Google translator because it is in Chinese.

Castlevania X yzb optimized version (depends on 4M RAM accelerator card)

Summary:

This version is optimized on the basis of the Japanese version. If you want to run it on a non-Japanese version of the host, please apply π to patch M to the image.
This version is only optimized for reading the disk, the sound, picture, operation and other contents are the same as the original version.
This version requires 32Mbit (4MByte) expansion accelerator card in order to run (simulator please put π into the settings to choose a good expansion cassette, A please
Insert the expansion accelerator card), if it is not set or not inserted, there will be an error prompt interface after the Sega authorization logo after startup
The source image before modification meets the following data verification:
Http://redump.org/disc / 3849 /

Mirror for release Use Clone CD format
If you need to use a software other than Clone CD to burn the disc, please directly select the file with the suffix CUE in the burning software.
If you need to use virtual hardware for optical drives like Rhea / Phoebe, you don't need to convert the format.

Modify the description :

Corrected the algorithm of the acceleration card file verification after restart.

Compressed files, optimized reading.
Significantly speed up the response time of calling out the three characters and exiting the map.
Significantly speed up the response time of Aruka to press the start button to enter the menu and exit the menu, the effect is very obvious in the archive room (other exit places)
(Single time black screen depends on the complexity of the current level is slightly different).
Press the shortcut key in the game to directly call up the map:

L Richter and Maria buttons can directly call up the map, press L or B on the map interface or directly exit the map to return to the game, will not pause.
Because the L key of Arucado uses the third-hand prop, it is changed to press the B (jump) + R (back) key to bring up the map.
3 Arukado is on the map display interface, press B to return to the game, press L to go to the menu interface.

Optimized the smoothness of the character's movements (to avoid frequent repeated decompression of the character's movement sequence frames)
Other modifications and optimization:

You can press the start key to skip all plots and cg animations (the default pass is once)
Optimize CD file arrangement
The dummy file filled with 100m on the innermost side of the mirror
The dummy file filled with 100m on the outermost side of the mirror

Supplementary instructions for reading data:

Enter the game for the first time after booting, on the Loading Loading Now loading screen (you can handle Loading MB
MB MB MB MB MB MB MB General MB MB -20 -20 -20 -20 -20 -20 -20 -20 -20 -20 -20 -20 -20 -20 -20 -20 -20 -20 -20 -20 -20 -20 -20 -20 -20 -20 -20 short. This is a one-time, if you do not shut down, download
It will not be read again. Please do not reset or shut down at this time. When you come to this screen later, the loading time will be faster than the unoptimized original version.
In the game, except for level switching, entering the boss room and clearing, do not read data at other times (including going to the library, transmission point, character death and
(The title screen returned after death, but the sound and animation AVI file data will still be read)
The level of the game in progress and the reading speed of the boss room are slightly faster than the original version
Thanks to the following people for their help. Without them, there will not be this optimized version (in no particular order)
Glf999, Ken, megavolt85, SONIC3D, sky0611

*Thanks for the hard work of the following people to test on the actual machine (ranked in no particular order)
