Today we are very proud to present a new firmware update: GATEWAY ULTRA 3.5!

Summary:
* Cheat code support
* Updated emunand support for 10.3 for Old 3DS

We’ve heard your prayers and here it is! Cheat code support for GATEWAY 3DS!

First things first. Our current cheat library is very small and should be
considered more as a proof of concept than anything else. We need you,
cheat hackers and cheaters around the globe to hack us some cool codes.

How, you ask us? That is a question we will soon answer, STAY TUNED. 

And as always, support the innovators not the imitators and ENJOY!

PS: We have noticed some serious and dangerous flaws in an unofficial Gateway emulation plugin,
and we strongly urge to cease using this plugin and only use GENUINE Gateway! You have been warned!
HOW TO USE CHEATS
=================

1. Simply copy the folder “cheats” into the root of your microSD card that will go into the Gateway RED card.
Each file inside the cheats folder will be of the format <TitleID>.txt where TitleID is the title id of the game.

2. Boot into Gateway mode, and press SELECT to make the Gateway game selection menu appear.

3. Select your game and then press Y to enter cheat mode.

4. Enable the cheats you want and then press START to load the game.
CHEAT CODE FORMAT
=================

The GATEWAY 3DS cheatcode format is based on the old ActionReplay DS
code format, the one you all know and love! We added some code types
for your convenience as well!

The following code types are supported:

NOTE: default value of offset and data registers is zero.

Memory Writes:
0XXXXXXX YYYYYYYY ? 32bit write to [XXXXXXX + offset]
1XXXXXXX 0000YYYY ? 16bit write to [XXXXXXX + offset]
2XXXXXXX 000000YY ? 8bit write to [XXXXXXX + offset]

Conditional 32bit codes:
3XXXXXXX YYYYYYYY ? Greater Than (YYYYYYYY > [XXXXXXX + offset])
4XXXXXXX YYYYYYYY ? Less Than (YYYYYYYY < [XXXXXXX + offset])
5XXXXXXX YYYYYYYY ? Equal To (YYYYYYYY == [XXXXXXX + offset])
6XXXXXXX YYYYYYYY ? Not Equal To (YYYYYYYY != [XXXXXXX + offset])

Conditional 16bit deref + write codes:
7XXXXXXX ZZZZYYYY ? Greater Than
8XXXXXXX ZZZZYYYY ? Less Than
9XXXXXXX ZZZZYYYY ? Equal To
AXXXXXXX ZZZZYYYY ? Not Equal To

Offset Codes:
BXXXXXXX 00000000 ? offset = *(xxx)
D3000000 XXXXXXXX ? set offset to immediate value
DC000000 XXXXXXXX ? Adds an value to the current offset

Loop Code:
C0000000 YYYYYYYY ? Sets the repeat value to ‘YYYYYYYY’
D1000000 00000000 ? Loop execute
D0000000 00000000 ? Terminator code

Data Register Codes:
D4000000 XXXXXXXX ? Adds XXXXXXXX to the data register
D5000000 XXXXXXXX ? Sets the data register to XXXXXXXX
D6000000 XXXXXXXX ? (32bit) [XXXXXXXX+offset] = data ; offset += 4
D7000000 XXXXXXXX ? (16bit) [XXXXXXXX+offset] = data & 0xffff ; offset += 2
D8000000 XXXXXXXX ? (8bit) [XXXXXXXX+offset] = data & 0xff ; offset++
D9000000 XXXXXXXX ? (32bit) sets data to [XXXXXXXX+offset]
DA000000 XXXXXXXX ? (16bit) sets data to [XXXXXXXX+offset] & 0xffff
DB000000 XXXXXXXX ? (8bit) sets data to [XXXXXXXX+offset] & 0xff

Special Codes:
DD000000 XXXXXXXX ? if KEYPAD has value XXXXXXXX execute next block
