Title: Recognizing running program in C64 mode / on real C64
Post by: MIRKOSOFT on September 30, 2009, 10:43 AM

Hi!

I have simple Q:

Can I in code recognize that C64 program is running on real Commodore 64 or on Commodore 128 in C64 mode?

Thanks for every reply.

Yes, there is a way. See this post (http://www.commodore128.org/index.php?topic=531.msg1634#msg1634).

...can detect size of VDC-RAM?

'cause working with registers $D600/$D601 is possible and also accessing VDC-RAM...

Thanks.

Yes you can do that as well (there are several posts about it here on the forum) - head for the search function.

Hi Lance!

I know how to detect size of VDC RAM in C128 mode.
But how to do it in C64 mode?

Thank you for reply.
