Strange. I beat this game on Gens 2.10 and didn't notice any bugs. The only one thing: after beating the game you see black screen with music playing. I hacked palette and get strange logo with fax number. Here's how to get it: Open ROM in hex-editor, go to address $62B6 write 22BCC0000000700F209A51...

Well, of course I know that there are NO THE BEST compressors. Sometimes one is better, sometimes another. But one can be better more frequently. That's why we need complex criteria and take into account speed / size / RAM, etc. preview.bmp is not that case of data which you expect to decompress in ...

Here are some tests: http://www.fileden.com/files/2009/4/23/2415345/aPLib_tests.rar I made get_bit routine faster, so it's better to use my unit. Also I add 2 preprocessors definitions. Size of unpacker is 212 bytes (Macros version). It's old version of get_bit. get_bit: subq.b #1,d5 bne.b still_bit...

Hmm, it's interesting to compare such parameters of compressors like: Compression ratio / Size of unpacker (for 68000) / Speed (for 68000) / Used RAM / Used Registers. Competitors are, for example: RNC, aPLib, Hrust, BitBuster. I found only sources of BitBuster for z80/ARM. I have sources for RNC an...

I've tested some instructions and here's what I got: clr.b d0 - 4 clr.w d0 - 4 clr.l d0 - 6 (Gens shows 8 cycles) move.b d0,(a0) - 8 clr.b (a0) - 12 So, CLR really takes longer time than MOVE. We can check if CLR performs dummy READ with use of serial autoincrementing port, for example, VDP. But I d...

The catch is that they are not. Clr performs dummy read before it writes 0 What the ...? Developers' mistake? Normal CLR must not to make any "reads". Anyway, if it does, operation of CLR.B #0,RAM will take 4 cycles longer than it should without "read", so we can check this moment. ...Hmm, IIRC CLR...

the S-Factor had all MOVE #0 replaced with CLRs and well you know what happens when you CLR on VDP :P Why so? I thought MOVE #0 and CLR are working internally the same way if you look from the side of MMU or RAM. I mean if you perform instruction: MOVE.B #0,Addr or CLR.B Addr then next steps are pe...

VDP can scroll horizontally Planes of raster and even single lines, it has HSRAM for it. To make "veritcal sine" effect ("underwater") you should set VDP HScrolling mode to Single Lines and to write into HSRAM numbers which represents template of sine, for example: 0 1 2 3 4 4 5 5 5 5 4 4 3 2 1 0 -1...

As I understood from your 2 posts, you want to fully decompile specified game, right? It's good idea, but unfortunatelly it's very hard to implement. Also is there a debugger with a tracer in it where you can run the game for a while and then exit and it will say all the lines where it ran instructi...
