    If you are programming yourself, search eBay for such chips and check out the following Amazon programmer:


    • Ability to quickly and easily switch operations from MVS time to AES time. You play your favorite games as a home console version that allows you to use one of the additional game options that some games have.
    • Ability to easily change the location of the country (great for games that are disabled(see Blood USA in the “Region” section).
    • Access to DIP DEBUG and developer mode.
    • Do you want unlimited life or it could be energy … So read on in games with a built-in cheat engine that currently contains over 1570 cheats !!!
    • Hiscore offers cost-effective support for SMKDAN AES hardware (requires memory chip).
    • PICKnMIX (161in1 see required), menu in additional information.
    • If you are not very happy with the tips, you can finally fix right in memory at any time and add your own.
    • A jukebox with which you can play on your refrigerator with game music without sound effects through the gameplay from above. A good option if you want to organize your MP3s.
    • CRC32 ROM, which can be used to check if the ROM of the game drive is working.
    • Allow real US region (correct display of portions in the lower left and right corner of the screen, as in a real US BIOS.
    • Arcade VS-MODE support is known to be JAPAN Bios version 6. Switch this function to hard immersion 2.
    • PC-2-NEO, which offers the special ability to download downloads and marketing information from the system using an easy-to-create character string.


    • Switch the room for selecting links and vice versa. This allows you to have a full SNK joystick so you can do whatever you want.
    • Once the region and mode of operation are determined, the BIOS remembers the settings that you eventually change again (requires a memory card on AES hardware to work here).
    • Access to the Memory Commonplace Card utility, no matter what mode the BIOS is in (with a particular MVS regular BIOS, you can never access this menu very well).
    • Enter test mode at startup without having to connect JAMMA test mode clamps or manipulate DIPs.
    • Improvements in the TEST MODE menu and test screens for Universal Serial Bus.
    • Hide DEV location view email (and red warning screens) from some online games when running MVS hardware in console mode or bothLearn AES in arcade mode.
    • Take a look at the internal storage with the built-in storage viewer in mind. This is useful for tracking down errors due to faulty locations (multi-slot equipment) or even the car simply won’t start.
    • Ability to smoothly restart the device without turning it on incorrectly.
    • Consider the total fatalities in your unrepaired AES vehicle from Samurai Shodown V (see specials below).
