I don't *think* caetla has so many of the in-game features, like cheat searching and all that, you could possibly do it via catflap or XFlash (PC) by resetting the console and dumping the mem out before it's overwritten?

I remember there being similar GameShark code finders, but I dunno how compatible they are with an Xplorer running Caetla. For one, Caetla uses a different way to pulse/ack bytes over the parallel port even on Xplorer cart... but y'know, it could be incompatible in terms of both the protocol and the send/acknowledge routines.

Have you tried to see if it's possible to pause, dump memory and dump the VRAM under caetla with catflap while a game is running? If so you could knock up your own GUI to do the business in C# -it's ridiculously easy to get the comms up and running with the catflap source sitting next to you (just pay close attention to Send vs Send8). If it was to work, then I guess, just like XPlorer you'd have to start the game with cheats enabled or somethng?

Is it written in assembly btw, 'cause IIRC even an empty Psy-Q .exe is bigger than 20kb?

#include <stdlib.h>

int main()
{
	AddSIO(9600);
	printf("Playstation %s %d \n" , "debug",  1);	
	
	return 0;
}

I'd just logged in to submit the 0.24 update before reading these replies, so time was a little tight to make significant MCLauncher Changes - but there's more than enough space now for that and possibly more!
(standalone is 109kb now with MCLauncher as a plugin)
If I've missed anything I'll get round to it in the next update.


P.s. Bump for 0.24 - Auto Launch with Plugin and stuff.

It also seems that X-Flash will never find any ROMs on any CDs, it doesn't even spin up the disc to check it, but other than that, I absolutely love UniROM!

Its a bit messy but it works... Since the PSX runs on a little-endian processor, the library should also work properly when compiled for Win32 as well.

It is based off of one of the LZSS compression/decompression examples from this site:

So I'm really intent on having a standalone 128k version of UniROM that's as usable as possible - i.e. comes with its own recovery disk, can be reflashed by itsself, and offers both serial/parallel comms.
I get the feeling it'd be easier for someone with an old generic 128k cart to get something built with Unirom+PSXSerial than to build a Freewing and flash Caetla or other kinda card replacement.

I'm having that issue, I got the 8bit ISA comms card, Action replay and (I think) an xplorer card... and a net yaroze.
I don't really want to use the yaroze stuff (slow) and I don't want to buy a PC that's 20 years old

Does a USB parallel port work?
ie:

if so with which comms software? PSXSerial?
Any help would be appreciated.
Cheers

Just use your Yaroze DTL-H3050 serial cable with PSXSERIAL.
If your computer does not have a RS232 (male DB9/COM1) port, use a USB to RS232 adapter.

If you want faster transfers with faster debugging, you'll have to get yourself an old computer with a parallel (male DB-25/LPT1) port that supports SPP mode and use your Xplorer/Xploder with CAETLA. I'm not going to explain how to set that up, because it's been covered many times before on the forums (use the 'Search' bar at the top).

If you have an Action Replay V3, you don't need the Comms Link (ISA card) to use it since DATEL added the communication layer in the V3 itself.
