Yes I can. I must check my PD-ROMs on real hardware.

Not yet.

It may help: To study signals VDP I did this: did connect on RGB, blue and red left in their seats and green connected through buffer to the signals. For example, thats "bottom dots" goes strictly by signal CLK of VDP memory. Try yourself. Very interesting happens, when try "to watch" VDP memory sig...

I didn't know about how NAND or NOR works. http://www.byte.com/art/9606/sec8/art5.htm NOR ( see the figure ) is the leading technology today, and Intel is the major manufacturer. It organizes the memory cells in parallel fashion, with each cell's drain connected to a bit line, and many bit lines ar...

Awe man, last update to KMod? I had an idea for something I wanted to experiment with. I got a Smart Media card with my Genesis games on it in BIN format (raw dumps), and I was hoping if the emulator could be made to load it directly from the card, and not copy to RAM then run. It's an unusual requ...

Will you ever made an step by step trace mode in debugger? it's not possible with Gens since it does "execute code for X ms then execute code for HBL then...." :( I would like to do it but...do much hard work needed :( I don't even know how to handle step by step with these HInt and VInt : How to t...

Will you ever made an step by step trace mode in debugger? GENs have an little bug with debug information screen: when VDP in 32 tile mode - part of debug information not showing. But you made separate window to debugger. If you made step by step debug mode and break on memory access at address (any...

Not MD support that exceptions, but 68000 it self in MD. When I repairing one MD, 68000, it did double bus error and halts. With fully complies with the specifications.

oh...M68k engine...I never looked at it yet... I'll try to find if someone corrected this starscream bug. when you say "wrong decode", do you mean disasm output is wrong or it produces bug (like for move.l) ? (to know if it's a engine or print issue) Yes, just printing error. If press "Step" ("T" b...

I have the "Beyond Oasis" (aka "Story of Thor") cartrige, wich do this too.

Looks like a byte swap was missed... but good friggin' lord! I'm not use byte swapping. This is long word reading by byte. EDIT: Hmm... thinking about it a moment, if the above address isn't aligned and you're simulating the alignment error of the 68000, my code above will cause a fault on odd alig...

Emulator : see below. Windows : does not matter. Here is the problem : 1 : GENS's debugger wrong decodes ORI.W and some other opcodes. 2 : I found a bug in emulation M68K in MOVE.L (A0)+,D1. First time it's work fine, after some calculations it's read garbage in D1, but A0 is still correct. MOVE.B ...

The only problem I can think if is my flashcart which is just 2x 16mbit ROMs and a custom EEPROM mapper, no SRAM of any kind... It seems that I have to apologize to you. Indeed, at one NTSC console hangs happening. It turned out wrong expectation of Z80 bus... :shock: Bug fixed, take here: http://t...

I'm talking about Gens KMod, sorry.

I've got it. But before make overclocking, will be better to correct current bugs. Especially in the debugger.
