Arcade Lifestyle / Galaxian Savekit incl. a Scoretable
« on: July 22, 2015, 08:49:27 PM »
OK Guys,

i just want to know (before i do a lot of work for nothing)

is there any interest for a namco (or midway) galaxian highscore save kit including:
* the possibility to enter initials
* a scoretable (maybe 5 scores)
* software dip-settings

Arcade Lifestyle / Asteroids Online Kit - i could not resist....
« on: June 29, 2015, 08:23:01 PM »
i really do love vector-games very much....

after finishing the online-kit for asteroids, i could not resist to add some nice "features" (i grew up in the atari st demo-scene)

i thought...if you have to wait until the kit is online...you can show something :)

have look here: :arrow:

Arcade Lifestyle / Donkey Kong + Pauline - Dual-Version
« on: May 18, 2015, 02:20:43 PM »
a few weeks ago i found the donkey kong arcade pauline hack

http://www.multigame.com/dkp_arcade.html  - http://www.multigame.com/dkp_arcade.html

and fell in love with that version.

first i want to mention here that all of the original arcade work belongs to Clay Cowgill. Without his work mine wouldn't be possible.
The original idea is from Mike Mika.. he should be mentioned and thanked as well!

after reading the information i found an interesting statement:

..."There's a lot of unused space in the Donkey Kong graphics ROMs. "...

here i thought - maybe there is enough free space to combine both graphics. i knew that there is more to do than just swap the grafic data.
i wanted to create a switchable version (to increase the woman-acceptance-factor) ;-)

i have the source-code of DK for my online project so i gave it a try.

first i downloaded the rom-patches for Pauline and made a original Pauline version.

then i downloaded turaco (it was not that easy to run that program on Win7 64bit) and extracted both graphic-images.

there i saw, that there is really enough free space to combine both versions.
DK has space for 128 Objects, but only 92 are filled with graphics.
that means 36 free spaces.

there are 29 changed objects for the Pauline-Edition - so it should work :)

after combining both graphics i started to modify the dk program.

the easiest way was a conversion-table for all 128 sprites (most of them will be unchanged).
e.g. when the program wants to show sprite #0 (mario), it should show pauline (sprite #53)


spritetable:
          defb #53,#54,#55,#56,#57,#58,#59,#07,#5a,#5b,#5c,#5d,#5e,#5f,#67,#68
          defb #69,#6a,#6b,#6c,#6d,#15,#16,#17,#18,#19,#1a,#1b,#1c,#1d,#1e,#1f
          defb #20,#21,#22,#23,#24,#25,#26,#27,#28,#29,#2a,#2b,#2c,#2d,#2e,#2f
          defb #30,#31,#32,#33,#34,#35,#36,#37,#38,#39,#3a,#3b,#3c,#3d,#3e,#3f
          defb #40,#41,#42,#43,#44,#45,#46,#47,#48,#49,#4a,#4b,#4c,#4d,#4e,#4f
          defb #50,#51,#52,#53,#54,#55,#56,#57,#58,#59,#5a,#5b,#5c,#5d,#5e,#5f
          defb #60,#61,#62,#63,#64,#65,#66,#67,#68,#69,#6a,#6b,#6c,#6d,#6e,#6f
          defb #70,#71,#72,#47,#71,#07,#76,#77,#6e,#6f,#70,#7b,#7c,#7d,#7e,#7f

the colors must be altered as well, so again - a table:

colortable:
          defb #ff,#ff,#ff,#ff,#ff,#ff,#ff,#0d,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff
          defb #ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff
          defb #ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff
          defb #ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff
          defb #ff,#ff,#ff,#ff,#ff,#ff,#ff,#08,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff
          defb #ff,#ff,#ff,#09,#09,#09,#09,#09,#09,#09,#09,#09,#09,#09,#09,#09
          defb #ff,#ff,#ff,#ff,#0c,#09,#01,#09,#09,#02,#02,#02,#02,#02,#09,#09
          defb #09,#01,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff,#ff

...and sometimes i had to convert it back again for math-operations:

spritebacktable:
          defb #00,#01,#02,#03,#04,#05,#06,#75,#08,#09,#0a,#0b,#0c,#0d,#0e,#0f
          defb #10,#11,#12,#13,#14,#15,#16,#17,#18,#19,#1a,#1b,#1c,#1d,#1e,#1f
          defb #20,#21,#22,#23,#24,#25,#26,#27,#28,#29,#2a,#2b,#2c,#2d,#2e,#2f
          defb #30,#31,#32,#33,#34,#35,#36,#37,#38,#39,#3a,#3b,#3c,#3d,#3e,#3f
          defb #40,#41,#42,#43,#44,#45,#46,#73,#48,#49,#4a,#4b,#4c,#4d,#4e,#4f
          defb #50,#51,#52,#00,#01,#02,#03,#04,#05,#06,#08,#09,#0a,#0b,#0c,#0d
          defb #60,#61,#62,#63,#64,#65,#66,#0e,#0f,#10,#11,#12,#13,#14,#78,#79
          defb #7a,#74,#72,#73,#74,#75,#76,#77,#78,#79,#7a,#7b,#7c,#7d,#7e,#7f

i don't want to get too technical here - there other small things i changed, e.g.:
mario (as hostage) is much smaller than pauline - so i lowered the "help"-text one line.

and finally i put a "switch" that all those changes can be switched "on" and "off".

hardware-modifications:
* change 5 of 6 graphic-eproms
* and a savekit with the new program

here are some screenshots:

All the rest / Hello world, i am Jochen :-)
« on: September 05, 2013, 11:24:47 AM »
Hello to all here,


I am Jochen Hippel - another arcade-infected enthusiast.

A little bit about myself: (edit: i didn't thought that it would be that much)


Born in 1971

~1982
Saw my first arcade (Pac Man)
Played a lot on my Atari VCS
~1984
Got my first Computer, a C64. started to be interested in programming... Basic first, 6510 Assembler later.
Found out that Video-Game-Music (esp. on the C64) was the thing i loved most.

~1987
A friend convinced me to get an Atari ST instead of an Amiga.

Basic on Atari ST was quite shitty, 68000 Assembler seems to be the solution.

Arrived at the Atari-St-Demo-Scene.

~1988
Arrived at Video-Game-Industrie- programming Music for Computergames e.g. for Rainbow Arts, Thalion, Hewson
(Games like Turrican (Atari ST), Wings of Death, Amberstar, Rings of Medusa and many more).

Cnverted complete games from Atari ST to Amiga for Thalion.

~1994
stopped working with Computers.

much much later....

~2000
got my first PC

~2002
started "programming" or is it called "scripting" again..this time with php, javascript html,Java

~2012
Tyrem, a very good friend of mine, infected me with the arcades...

Sometimes i feel like i child even though i was not that much involved back then - when i was a child.

Got my first Cab - a German Donkey Kong(Japan-RomSet). i brought it up to the 2nd floor. Heavy like hell - i am not the youngest anymore.

Got interestet in electronics because the CRT of the donkey kong (a Hantarex) was blown. Luckily I managed to repair it :)

Got my 2nd CAB, a original Zaccaria Frogger. Love that game!

Got a lot of PCBs

2013
Found out that it is possible for those Games to let them save the highscores....
I also found out that playing the game and competing with others(sharing with friends) is much more fun because:
A good friend of mine kicked my highscores in Frogger, Time Pilot and Donkey Kong. THIS CAN NOT BE!!!
At least i took over the highscore of donkey kong again... but i still have to practice in Frogger and Time Pilot.

Recent project: Tyrem and myself trying to create a little piece of hardware to save highscores and send it to the net...

This idea is not new, we just put together two already existing things: A "highscore save kit" and a hardware that connects to a Network (e.g. internet)
The installation of our hardware should be as easy as it can be - because we all love our babies and we want to keep them as original as it can be.

There are a lot of possibilites like the highscores and dipswitch-settings can be uploaded to a website or to a scoreboard in the game-room.

5 days ago:
i started with part 1: Highscore-Save-Kit.

First project: Wizard of Wor.
I had to extend the program code to enter initials. I have never programmed Z80 assembly-language before...

yesterday:
This part is 98% completed. WOW is now able to enter initals :-)

Now i need to build the hardware to save the scores on a EEProm

Next part after that will be: adding network.

Tyrem already opened a thread about that project - smore details in there soon.


And finally it is nice be here along with many like-minded people :-)


greetings from germany

Jochen
