About LinkBacksDopo le numerose lamentale nei confronti del TX per non aver rilasciato il sorgente del CPLD CODE sviluppato per le console corona 16 mb, pochi minuti fà il team si fà vivo e rilascia l'intero VHDL !

Il team inoltre ci ricorda che l'interfaccia grafia di Xell (GUI) non funziona, ma è possibile recuperare la cpu key tramite collegamento LAN, precisa che sicuramente a breve i coder di Xell risolveranno questo!
Speriamo in una conferma dal nostro caro Etheral!
