Download Ys: Memories of Celceta - mp_9999 Save Files File: Ys-MOC-mp_9999-Saves.zip (168 KB) (info) |
There are two save files in the archive above: one for the Vita, and the other for the PC version. Both of them are set to load the player in the test map, mp_9999.
The .arb file necessary for loading the map on the PC version (explained below) is also provided for convenience.
Restoring Access on PC#
The .arb file necessary for loading mp_9999's contents was removed in XSEED's PC port, but can be re-obtained from the Vita version. Follow these steps to restore access:
- Copy mp_9999.arb from
\map\mp_9999\from the Vita version. Naturally, the file must first be decrypted in order for this to work. - Go to the PC version's folder and enter
\lang\. Enter the folder of your preferred language. (In this example the\lang\endirectory will be used). - Create a folder in
\lang\en\map\named mp_9999. Paste the copied mp_9999.arb inside it, and it will be possible to load mp_9999's model and debug menu again.
Creating the Save File#
In order to create the save file yourself, follow these steps:
- Make a save file that is saved somewhere indoors. The inn in Casnan is a good choice for this.
- Open the save file in a hex editor and head to offset 0x0006f20 in the Vita version, or 0x0006f48 in the PC version.
- Replace the bytes starting from here with 6d705f393939392f6d705f393939392e617267. If you were saved in Casnan's inn, the bytes to replace would be 6d70313231312f6d70313231312e6172670000
- Note: You can also type over the string at this offset in the text view. Simply replace the current map's name and .arg filename with "mp_9999".
- The save file's checksum needs to be fixed now. A checksum fixer by unknowndatax can be used to resolve this. As a side note, this tool works on each of the Yamaneko Engine Ys games, including Ys Seven and Ys VIII.
- The save file can now be copied back to the game and loaded up. Upon loading, you will spawn in the test map.
The Cheat Engine method detailed on Ys VIII's page can also be used to gain access.
mp_9999#
This is the only test map that remains in the Vita version and XSEED's port. The model of this map is an enlarged version of the map of Celceta. Upon loading the area, the debug menu found in \script\test.bin is called, which has several options for testing the game. This map would later be carried over to Ys VIII: Lacrimosa of Dana with a new debug menu.
Regardless of your current party setup the only active character will be Adol, though all the other party members can be added back via the Camp Menu.
In the Vita version, exiting the debug menu will cause character models to become partially transparent, and the lower portion of the screen will be covered by a black layer. This oddity does not occur in the PC port.

Eleven spheres are placed on the map that teleport the player to different areas.
Removed Test Maps#

The four green spheres on the upper portion of the map led to test areas that are no longer in most versions of the game. Attempting to enter them will spawn you in a black room where you instantly fall to your doom. These maps do exist in Joyoland's port, however.

Functional Warps#

The other seven spheres have functional destinations, and their placements on the giant map of Celceta are accurate to the in-game world map. The two yellow spheres represent towns, while the blue ones are field areas.

Debug Menu#
As stated above, the debug menu is called upon entering the test map mp_9999. Several choices are available from the initial menu.
The menu was not optimized for the PC version, resulting in the scrollbar being displaced at resolutions not approximately equal to the Vita's 960x544 display.


Battle Test on Grasslands#
Spawns a party of Adol, Duren, and Karna in the middle of the first area of Beast Plains.
For Sub Memory Event Checking#
Has several options that are supposedly used for testing some of Adol's memories, but they don't function properly anymore, as you stay in the test map after selecting them.


Balance Test#
A menu with a selection of character levels and areas to choose from, clearly meant for checking the game's balance. This menu is only half-functional, as character levels are not modified. Selecting an area will spawn you there with a predetermined party with their current stats.




Event Jump#
As the name suggests, this menu lets you jump to various events in the game. Each option opens another menu that lets you select a specific point in the selected chapter.


Boss Test#

Lets you choose a boss to fight from four sub menus. Their model ID is listed alongside names that often differ from what's actually used. Note that the used boss names were directly translated from the Japanese version, so a majority of these names are earlier iterations or placeholders.
Unlike Balance Test, these choices actually adjust the levels of each character accordingly. A predetermined party is also assigned for each boss fight.

Emotion Test#
The camera zooms in on Adol and each emote and speech bubble are played out above his head. The camera does not reset itself after this, but will be readjusted after entering another map.
General Related#
Selecting this will bring up another menu.
General Related#
Same name, different menu. Doesn't have any apparent effects, but based on the choices, it could have been used to set the player at certain points in the game or set flags.



Quest Related#
Has options for testing sidequests, such as spawning all quest monsters, making all quests available, and displaying a quest completion test message.
Memory Fragment Related#
Lets you obtain all of Adol's memories, play back "The Forest Siblings" memory, or jump to the point in the game where Ozma joins the party.
NG+ Flag On#
Does what it says on the tin. Enables New Game+, allowing bosses to be fought from the Memories menu.
Other Useful Functions#
A menu with options for unlocking all journal topics, skills, monuments, party members, and testing every shop in the game. There are two other options that toggle something called "SF_EVENT".


Test#
Just displays a message saying "Dig up as much ore as you can in the time limit!"
Yamashita Test Use#
Four simple test messages spoken by Adol will be displayed, followed by a menu that pops up afterward. These initial test messages are not present in the Japanese version.
"Yamashita" refers to one of the game's programmers, Hideyuki Yamashita, whose name can be seen in the credits.
Enemy Elimination Test#
Adds Duren to the party and sets Adol on fire, quickly killing him off.
Puzzle Test#
Provides options for testing the touchscreen-based puzzles.
Font Test#
Displays a message from Adol that is meant to test fonts.
This message is incorrectly rendered in the English version, but the font it is trying to test can be seen in the Japanese version, which is used by the Roos.

Test During Memory Event#
Duren is added to the party, and all battle elements are disabled, simulating how playable memories function.
Choices Test#
17 choices are displayed that don't have any functionality, but their text is the real interesting point. It defaults to Choice 5: THANK YOU MARIO. 
Choice 1
Choice 2: A long journey begins
Choice 3: This is Chinatown
Choice 4: You got me

Zapping Test#
Tests the screen effect for when Adol is having a flashback.

Adol walks up an imaginary incline. He is dropped back down to the map afterward.

Plays out several weather effects.





SE Fade Test#
Plays a sound effect that fades out, then back in.

Revisional Differences#

|
To do: |
PS Vita#
The Japanese Vita version received an update that, among other things, improves the controls on the PlayStation TV. Although the US version was later made compatible with PS TV, these enhancements were not included.
Windows#
XSEED's PC port added Japanese voice acting in a February 2020 update.
