[Coco] MAMOU bug?

[Luis Antoniosi (CoCoDemus)]

Hey Steve,

Let me ask you one thing. The games you made for the coco, are they public
domain ? Because they are all wide spread on internet like coco archive or
.vhd images but they aren't available from your web page or even L. Curtis
Boyle game list. What makes me think they aren't in fact PDs.

Regards,

Felipe.
