 # PS1 Power Replay Datel clone - RE Notes
 
+## DISCLAIMER
+
+Any use of this project is **under your own responsibility**.
+You will be responsible of checking the correct construction and functionality of your board.
+By using this project You will agree that I cannot be held responsible if it will destroy any of your devices, damage your computer, burn down your house or whatever.

 ## Introduction
 
-I found one of these cloned Datel cheat carts for PlayStation 1 in a box of junk at a flea market.
-I decided to reverse engineer it just for fun, and maybe to build a better variant of it.
+This board is a reconstruction (with a few improvements) of a clone of a Datel cheat cart for PlayStation.
+This project builds upon the work I uploaded in [this repository](https://github.com/hkzlab/PS1_PowerDeplay_Datel_RE) repository regarding the reverse engineering and mapping of said clone.
 
-![Screenshot of the traced PCB](pics/traced_board.jpg)
+This device can be used with the original (provided) EPROM dump, or with [unirom](https://unirom.github.io/).
+
+I replaced the crappy zener-diode power regulation of the original clone with a proper linear regulator, plus the DB25 connector was replaced with an IDC connector.

+## Notes
+
+The PCB was fully disassembled, scanned, and traced to reconstruct the schematic.
+It's a simple dual-layer board containing a diode, a PLD, an EEPROM and a transceiver, plus a few passives.

 This IC was protected on my board, so I proceeded with an analysis of the signals and their combinations.
