Hi, Sorry for the late reply. X-killer is an old close source tool from 1999, see attached files. I don't really have any technical knowledge regarding the cheat DB management/encryption. Maybe you could try reversing X-killer itself if that could bring some answer ? ... Thanks. I may search for so...

PCB and shell images updated for the 3.18 X-T Pro DX in previous post. You may want to join the Discord server at some point, where it may be more convenient to discuss what you asked here . :) Thanks, I just joined there. But a little busy these days. I will ask related questions there when I'm in ...

... Next i tried flashing my dump and yours to a Xplorer FX that has an ATMEL AT29C040A-12PC 512K eeprom and it worked fine there. Can you check which kind of eeprom the device you dumped it from has ? ... It dumped it from an X-T Pro DX with an ATMEL AT29C040A-12PC ROM. In DIP package. And the dat...

Thank you very much for the dumps, i'll check them when i get free time. :) 2. There are user-added cheats found in the last 128KB section, too. I'm not entirely sure about this. Since original .fcd only cover the first 384Kb area for the rom program/cheat db, isn't the last 128Kb chunk reserved fo...

Dumps from known brand new carts would replace ones from used ones. As for used carts, any missing dump is welcome since it's better than having nothing at all. The current romset have those XT roms: X-Terminator PRO (Japan) r2.14 PRO 1999-02-17 [!] // Source : Original FCD. X-Terminator PRO DX (Ja...

Hi, This header data isn't part of original .fcd files . It's created at first boot and/or while accessing the VMS function for the very first time. ... Would you happen to have some currently undumped XT rom among your devices ? :mrgreen: Thanks for confirming that the tail region can be initializ...

Here is the schematic diagram of X-Terminator Pro DX (with a single 512KB ROM). For the twin 256KB ROM version, I still need several pin connection info. If anyone has this model of Xploder, and eventually has a multi meter with short circuit test feature, please consider do the following tests: * P...

The tail of last 128KB of X-Terminator Pro DX(JP) stores header data and should be dumped if possible. I noticed almost all dumps here missed that. The good news is based on multiple X-T Pro DX I have checked. The last 8 bytes header data are always: 56 4D 53 46 00 00 00 00 // (VMSF in ASCII charact...

Additional notes on both the original one and the knock-off: The GB ROM is mapped to 0x1F040000-0x1F04FFFF. The GB_A0-A14 are directly connected to PS1_EXP_A0-A14. So there should be no problem for software in direct access to 0x0000-0x7FFF region on cartridge address. Assuming we expect the emulato...

Add 2 schematic diagrams for this old topic, the original Japanese version, and the Innovation clone. In image format and vector pdf format. Notes on the Innovation clone: There are 2 switches on this cart. The lower one (H8 in the schematic): Switch to the upper position(GND) for the Cheating featu...
