+
+---------------------
+
+Egghunt by Invi Image
+
+PCB marked "Invi Image Co. 1995 IZ80B-1"
+The pcb has poor quality and resemble a bootleg.
+
+2x Z80
+1x AD65 (oki 6295 probably)
+1x OSc 12mhz
+1x OSC 30mhz
+1x FPGA
+2x Dipswitch
+
+Note: rom 3 has the 16th pin overlapped and soldered to 15th....it seems it's a manufacturer choice since pin 16 on the socket is not connected with any trace on the pcb
+I dumped it with this configuration. In case I'll redump it desoldering pin 16 from 15
