A fairly decent handheld Famiclone with 152 games built in (many of which are duplicates and ROM hacks).
Test Screens#
Main Device Test#
A standard device test (for visuals, controls and sound) can be accessed by holding A + B before the title screen loads in. It is credited to Aaronix (a Famiclone manufacturer from the late 80s), and its CHR is copied from Space Invaders. Somewhat ironically, this shows the RS-1's incapability of running some of the sound channels on real hardware...
Press Key Test#
A more basic controller test mode is in the ROM somewhere around $068010; it is accessed by holding A, B, Start and Select simultaneously. Oddly, its graphics seem to have been copied from the SuperArcade 110's menu, another Famiclone plug & play.
Unused Games and Programs#
Super Mario Bros. Variant#
Present at $260010 (PRG) and $254010 (CHR). This version is the common "2" variant (ID LB-35) seen on the majority of Famiclones, but the RS-1 uses the original unhacked Nintendo version instead.
Star Force#
An unhacked ROM, present at $1D4010 (PRG) and $1D8010 (CHR). On the two earlier revisions of the RS-1, this game is used in the menu; on the third revision, however, Pizza Boy appears in its place instead.
Revisional Differences#
There are six known revisions of the Game Prince RS-1's software, each with various differencesː
- 2012 Modelː Features an 89-in-1 game list; the list is in English only, though has several typos (e.g. Angry Birds as "Angry Brid"). It has a unique menu design featuring mushrooms; this design would later be reused in the "RS-16" handheld.
- 2013 Modelː Effectively the same 89-game list as the 2012 model, but the menu has been updated to the newer design with the bookshelves. This model adds an English or Chinese menu selector, and the vaguely Mario-ish title screen. This revision would later be used as the list seen on the MGP Slim Station 8 plug & play.
- 2014 (?) Modelː The first 152-in-1 model, built off of the 2013 version's code. It uses an 8MB ROM to hold the extra games, while the prior models used 4MB ROMs. It also attempts to remove the Chinese menu, unsuccessfully as noted below.
2015 Modelː The most common form of this device. Adds the "152 in 1" tag and the "Please prass the START key" line to the title screen.- "E-Mods Gaming" Modelː In addition to having an additional "E-MODS" logo on the front of the console, this version adds ten more games to the end of the list in the 2015 model, several of which are VT03. The Chinese menu is still not properly selectable, and has not been updated to show the additional ten games. For unknown reasons, the VT03 games do not display properly if playing through the TV connector; an issue seen on several Famiclones from around this time.
- "Qingshe QS-4" Modelː Similar to the prior model, this takes the 152-in-1 model and adds thirty additional games to the end. Unlike the E-Mods version, they are not VT03 games, being comprised of standard NES/Famicom releases and some older bootlegs (including Somari and Pocket Monster).

Hidden Chinese Menu#
In the 2014 Model and onward, if Start is held before the title screen loads in, it is possible to accidentally choose the Chinese menu. It's also faster to navigate, for some reason. This oddity seems to be due to a sloppy attempt of trying to remove this Chinese menu entirely; effectively from the developers forgetting to perform a one-byte code change. Changing byte $7b050 from 01 to 02 will prevent the Chinese menu from loading in.
