Moth-Line v1.01 is now available for patreon supporters with the following changes: ;; v1.01 ;; ;; Score line shown on first load ;; Highscore added ;; EEPROM load/save for highscore ;; BLUE Robot turns ORANGE shortly before turning RED ;; Score points float upwards from dots/pills/ghost kills ;; Intro splash screen improvements ;; EYES sprite changed to be more visible ::

You're correct, I forgot that I was drawing them behind the background sprite to get the desired behavior.

Hello, I saw this code in another book, for initially clearing memory; ldx #$ff lda #$00 clear: sta $00,x ; when x=#$00 it doesn't get stored into memory location $00 due to the "bne clear" dex bne clear With above code Memory location $00 is left uncleared? Would this be a good solution? ldx #$0 lda #$0 clear: sta $00,x dex ;1st time through loop, x now = #$ff bne clear

Fantastic work, James! I look forward to checking out any future builds! Regarding a physical release, why not swap out the sprites for Pac-Man and the ghosts with your cats? You could call the game, Treat Time.

I haven't checked it yet, but there should be a difference if the sprite is out of the right or bottom boundary compared to upper or left (if normal drawing is used).

It's a common mistake. The original device was just called SIO2PC and provided a standard serial port DE-9 interface for connecting to your PC. So, the device you're referring to is just that with a USB interface instead of a standard serial interface (well, USB is serial too... but...). Here's the device that's properly referred to as an SIO2USB.

SUZY does burst read, but no parallel or out-of-order processing. And no pre-fetching of the next SCB.

… and a PAL release in sight? 😃

Thanks for the spot. You are correct, I am referring to the SIO2PC-USB device. I noted from a little googling there seemed to be more than one device people were calling SIO2USB, at least one of which was a similar cable to PC as opposed to the flash solutions you mention, which I saw referred to as SIO2SD. I certainly don't want to add to any confusion, so have updated description of video and edited contents to reflect my error.

Yes, SUZY skips it, so there is no effect on the drawing time, but I think that the loading time of the sprite data into SUZY is different if the sprites are chained or not. If I remember well, reading the Lynx patents it seems that SUZY has some data buffer in it and at low level it should prefetch some data for the next sprite while it parses the current one. Is this correct?

A sprite off-screen is not drawn at all. SUZY skips it. So the same sprite takes different number of cycles whether it is fully, partly or not inside the 160x102 pixels of the render buffer.

Hi guys, Back with NeoGeoNow on more on what he has to say. Will there be a season 3 for King of Fighters XV? Anthony...

Thanks for the clarification. So basically I should consider Capcom+ HDMI vs better battery life. Saw a deal for the XPR for 110 euro so I might just go for that

Did Brad at BEST have any? DavidMil2

...and Video Pinball.

Hi guys, Nalua Studio @NaluaStudio What do you think our heroes (Candy, Golem & Loony) are up to in this wonderful sneak peek of one of the newest cutscenes in Vengeance Hunters? 1.

Hi guys, Snkmvsx@MVSXHOMEARCADE Hong Kong Electronics Fair(Spring Edition) SNK NEOGEO games hold a special appeal for them! Fair #HONGKONGFAIR 4:30 AM · Apr 17, 2024 Anthony..

You already know how to do poke and peek in Pascal, with the dual data type. Poke the VDP read address port to the VDP, then peek the VDP read data port from the VDP. If you want to write to VDP RAM or to VDP registers, you need to set the second or first bit in the address. Remember that UCSD Pascal can do bitwise logic functions by using the odd and ord functions. So you can do VDP_address := ord(odd(16384) or odd(your_address)); where both VDP_address and your_address are integers. That will set the VDP address for a write (which you don't need for GCHAR, of course). Also note that you'll need to create a swapbyte function, but there you can do a dual data type with an integer and a packed array[0..1] of byte, where byte is 0..255, to handle that. A word of caution! In the example above the constant 4000H is represented by the 2's complement decimal number 16384. If you want to get the equivalent of 8000H into a decimal number, you can not use the constant -32768! Since that number can't be negated without an overflow (there is no +32768 in the range of 2's complement 16-bit numbers) it will be handled like a long integer constant, occupying two words, not one. But you can use 32767+1, as UCSD Pascal does no overflow detection on integer arithmetic. As long as you don't divide by zero, that is. Note that for this direct VDP access to work you need to manually set the code type to M_9900, since if it's M_PSEUDO then the code usually will be loaded in VDP RAM. If you then change the read address the PME will get lost about where the code is. The PME will only set the VDP read address when performing a jump. If you link in an assembly procedure into your Pascal program the linker will set the code type automatically, since assembly can't run from VDP RAM. But the compiler can't know which memory you'll access in a Pascal program, so there it's not automatic.

Ah! Great to know Dopey. I really would like to see the end results towards it. You're welcome brother man. Glad to have you aboard and always a pleasure to read your postings that you share with us here on the Neo-Geo thread and throughout AtariAge. Can't wait to see your need title you purchase soon for your unit for sure. Thinking of adding a Neo Geo Pocket Color to your collection Dopy? Such an underrated handheld unit with fantastic games to play. Maybe @shane857 and our friend @Reloaded85x would like to add that handheld to the collection as well. Anthony...
