Valtric

Valtric
Developer: NMK Publisher: Jaleco Platform: Arcade (NMK Argus hardware) Released in JP: November 1986 This game has a hidden developer message. This game has hidden developer credits. This game has unused graphics.

Valtric is an interesting shoot 'em up that removes the autoscrolling associated with the genre and adds a (limited) jumping feature.

Hidden Message

One rather goofy message can be found in the main CPU at 0x16E70:

Message	Translation
MAIDO ARIGATOH GOZAIMASHITA KONO VALTRIC WA TENKABUTSUNO ISSAI HAITTEINAI OKOSAMANIMO ANSHINSHITE DASERU OKASHI DESU.... CHAN CHAN.	Thank you for your continued support. Valtric is a candy that can be safely given to children and contains absolutely no additives.... CHAN CHAN.

Developers Credits

Main CPU

There are six different credits strings in the main CPU. Here are the first three:

Address	Message	Address	Message	Address	Message
0x00E40	PROGRAMMED BY TOMMY NAKASATO	0x12390	created by Tamichan	0x131C1	(KK) NMK ALL RIGHT RESERVED 1986 PRESENTED BY JALECO

The second set of strings are all data block labels by Satoshi Nakamura.

Audio CPU

Two messages from Cheabow are in the sound CPU. The first is near the start of the CPU at 0x0069:

***This Sound Monitor Made By Cheabow.***
***Sound Effect Software Logic Design by Cheabow.***
***Music Data Transfer Logic Design by Cheabow.***
<<<<CAUTION: NOT A MANNER .... to be continue.>>>>

to be continue.

Turns out it ends on a cliffhanger.

Unused Graphics

	These Kanji tiles, found in the background and font graphics ROMs respectively, translate to "Yamaguchi" and "Origami", the surnames of the game's tile artists. (Translation: Divingkataetheweirdo)
	This NMK logo should have been put on the title screen, but nope. There's just a big Jaleco logo taking up real estate. (Source: Original TCRF research)
