Mike Arcade, on 27 August 2012 - 11:50 PM, said:A new build, excellent as always Esrael! I gotta say (and you probably get this a lot) I'm a big fan of your work, your hack of Sonic 2 Delta II way back when is what got me into Sonic Retro and Hack Games in the first place, I thank you for that and I'm so glad your back and around here again. If I see any bugs I'll report them.
Also, what's the music for Genocide City?
Destruction Power from Knuckles Chaotix (Bad Ending). -

I would have thought it's faster than the original Sonic 2 way, but it wouldn't be by much. But then this way, obviously uses more space (because you've inserted a table). You've used more space but a little bit of time saving. This is the type of thing where you ask yourself, "Speed or Size?"
If you're asking if it's faster then the S3K way, then it's definitely not. Your way, it still have to convert the byte into a word every single frame for every object (like normal Sonic2). And like said, the S3K way, it's already a word, and can just get on with things.

I do not know, but I would like to know this myself.
Thanks for reply.
I do know which your method is more faster, but I am trying to improve without doing a lot of change. -

About processor cycles / speed up I had a question.
For the time I don't want changing all object, but using a table will make any differences?
This Code
;=============================================================================== ; Sub Rotina DisplaySprite ; [ Início ] ;=============================================================================== DisplaySprite: ; Offset_0x01647A: ; lea ($FFFFAC00).w, A1 ; move.w $0018(A0), D0 ; lsr.w #$01, D0 ; andi.w #$0380, D0 ; adda.w D0, A1 ;------------------------------------------------------------------------------- moveq #$00, D0 ; Neto - Sonic 2D move.b $0018(A0), D0 ; Neto - Sonic 2D add.w D0, D0 ; Neto - Sonic 2D add.w D0, D0 ; Neto - Sonic 2D move.l DisplayTable(PC, D0), A1 ; Neto - Sonic 2D ;------------------------------------------------------------------------------- cmpi.w #$007E, (A1) bcc.s Exit_DisplaySprite ; Offset_0x016496 addq.w #$02, (A1) adda.w (A1), A1 move.w A0, (A1) Exit_DisplaySprite: ; Offset_0x016496: rts ;=============================================================================== ; Sub Rotina DisplaySprite ; [ Término ] ;=============================================================================== DisplayTable: dc.l $FFFFAC00, $FFFFAC80, $FFFFAD00, $FFFFAD80 dc.l $FFFFAE00, $FFFFAE80, $FFFFAF00, $FFFFAF80 dc.l $FFFFAC00, $FFFFAC80, $FFFFAD00, $FFFFAD80 dc.l $FFFFAE00, $FFFFAE80, $FFFFAF00, $FFFFAF80
vs original
;=============================================================================== ; Sub Rotina DisplaySprite ; [ Início ] ;=============================================================================== DisplaySprite: ; Offset_0x01647A: lea ($FFFFAC00).w, A1 move.w $0018(A0), D0 lsr.w #$01, D0 andi.w #$0380, D0 adda.w D0, A1 cmpi.w #$007E, (A1) bcc.s Exit_DisplaySprite ; Offset_0x016496 addq.w #$02, (A1) adda.w (A1), A1 move.w A0, (A1) Exit_DisplaySprite: ; Offset_0x016496: rts ;=============================================================================== ; Sub Rotina DisplaySprite ; [ Término ] ;===============================================================================
Another question? where we can find fast code execution tips? Ex:
lsl #$02, D0 ; one line
same results as
add.w D0, D0
add.w D0, D0
Two lines but less processor cycles.
Sorry for posting here, but since this port is for speeding up. I want to know, more tips for improving Speed with assembler.
Sometimes less code lines does not mean fast execution. -

That One Jig, on 07 June 2012 - 07:53 PM, said:Good to see you and Sonic 2 Delta back, Esrael! The amount of fixes you've put into this in such a short time seems to be bordering on superhuman! It's not necessarily a bad thing, but don't feel like you absolutely have to get new versions out ASAP.
Anyways, I've got one little thing I'd like to bring up. It's nothing game-breaking, just a bit aesthetically jarring/bugging:
...
Knuckles can climb "into" the GHZ loops, which can look a bit goofy. I was able to pull it off on the left side, too, but only ever one time. The right side I can do consistently. I'm not sure if this happens with any other zone's loops.
Then again, it seems like the entirety of GHZ can be quite buggy for Knux. It wasn't made with him in mind, after all.
...
KingofHarts, on 10 June 2012 - 04:08 AM, said:On some levels, points markers appear above the score tally results screen. It doesn't happen to all of them though. GHZ Act 2 is an example. I can look through and see exactly which ones, but itll take a little while, so don't expect it right away.
Also, a couple things to point out about going Super. Playing as Sonic or Knuckles on the SRAM works fine, but Tails is still not able to transform, and it still requires me to play the special stages even though I have all emeralds... also as a small nitpick, Knuckles can double jump to transform, while Sonic transforms on one jump... IDK about TAILS though. Was this intentional?
- New SRAM file with all Emeralds for Miles/Tails.
- Added double jump to transform into Super for Sonic and Miles.
- Hidden points at end of levels priority changed.
- Knuckles now can climb into Right Side of Loops.
- Boss fixes.
- Objects fixes.
