turbografx pal controller port fitting. need help with purchasing a tototek covertor.

i been enjoying the pal turbografx console and turbo everdrive which i purchased recentlybut the lead is kinda short and i had no luck finding extensions. now heres the thing. tototek are selling classic console convertors which allow you to use your ps2 dual shock controller on many classic consoles (the ps2 to saturn convertor i purchased from them works like a charm). so i was thinking i should get a ps2 to turbografx convertor but then i remembered i read somewhere before that the pal turbografx pads have a different pad input fitting. now i'm not sure what convertor to buy or if either of the two version tototek sell are compatible with the pal turbografx console ports. 1st theres the turbografx one which says same as pc engine but plug is bigger http://www.tototek.com/store/index.php?main_page=product_info&cPath=23&products_id=57
and 2nd theres the pc engine version which has the smaller plug http://www.tototek.com/store/index.php?main_page=product_info&cPath=23&products_id=51 any info would be great guys. i would love to get one of these convertors not only for the lead extension problem but the convertor also allows the ps2 pad to support street fighter 2 on the turbografx
