			=== Current findings (testing on MAME 0.251) ===
			==== Timing issue PAL vs NTSC ====

			The discrepancies are best shown with starting a pal device c128dp or c128p, so if you start up with a rs232 Interface connected to output into a file ans set to 1200 baud 8n1 in Machine configuration Menu:
			<pre>
			mame c128dp -w -user rs232 -user:rs232:rs232 printer -printout out128_bugged.txt
			</pre>

			and run a basic output loop to the rs232 (same results in c64 as in c128 mode):
			<pre>
			OPEN5,2,0,CHR$(8)
			FORI=0TO255:PRINT#5,CHR$(I);:NEXT
			CLOSE5
			</pre>

			this will result to a bugged output of
			<pre>
			hexdump -C out128_bugged.txt

			== Some Debugging Tipps ==

			I found it uswful to be able to have a channel from the device to the outside world of the host's filesystem.
			Thankfully some helpful people helped me to get a useful commandline set and configuration that enables a stable echange from the emulated device (c128* an also works with c64*) to the emulating host.

			<pre>
			mame.exe c128dp -w -user rs232 -user:rs232:rs232 printer -printout out128.txt
			</pre>

			Additionally you have to set the rs232 settings in the mame user interface (enable ''ui mode'' -> '''<tab>''' -> ''Machine Configuration'')

			[[File:C128MachineCfg.png\|200px\|right\|RS232 recommended settings for debug output]]

			The following BASIC snippet shows how you can print some data from the device to the file out128.txt (remember that the c128 does not use ascii encoding! so you will have to transalate the data later [some python snippet will follow later] )

			<pre>
			OPEN5,2,1,CHR$(8)
			FORI=0TO12:PRINT#5,CHR$(I);:NEXT:PRINT#5
			CLOSE5
			</pre>
			This snippet will print a 13 Byte long file which should contain the following Bytes:
			<pre>
			hexdump -C out128.txt
