Using more powerful processors allows the modchip to work with American, European, and Japanese PlayStation 1’s with a single chip. It can even patch the BIOS Note that this BIOS patch dont works with ATtiny chips.
## PsNee modchip source code
It supports the following microcontrollers:These chips fall into two categories, ATmega based chips, and ATtiny based chips. ATmega chips cost more, but allow for BIOS patching. ATtiny chips cost less. ATmega chips are also considerably larger in size, making them more difficult to fit into a system when compared to the ATtiny chips.

## PAL and NTSC incompatibility with your TV
In North America we have NTSC-U/C consoles and TV’s, and in Japan there are NTSC-J consoles and TV’s. Meanwhile Europe and some other parts of the world there are PAL consoles and TV’s. In the case of the PlayStation 1 the modchip can be used to unlock the console’s ability to output video for any region based on the game being played.
The problem with this is that not all TV’s accept all input signals. For example if you put a PAL game into your modded system and try to play it on an American TV you might not get any video on your TV.
To get around this problem I recommend buying a cheap [composite to HDMI converter](http://amzn.to/2lyOe0w). Typically these will take the weird analog signal that may be associated with a game from another region, and convert it into a nice and standard HDMI signal that your TV will display without any problems.
## Japanese consoles and video glitch with PAL games
Japanese consoles with specific clocks will produce bad video signal there are mods to replace the crystal with a pulse generator https://github.com/L10N37/PSXTAL for more information.
