Well I couldn't wait for you till you released a clean core file...so I have made one ;D  
It was more for the leaning experience, setting timers, interrupts, pwm etc. Much fun.

I have tested most that I could, no guarantee its bug-free in the first time. 😃  
Its for IDE 0017.  
I have the atttiny running @ 8mhz internal xtal.  
fuses:  
low=0xe2  
high=0xdd  
extended=0xff

Core file: [http://85.12.32.240/~superkoe/arduino/attiny84/attiny84-0.1.zip](http://85.12.32.240/~superkoe/arduino/attiny84/attiny84-0.1.zip)

extract it in arduino/hardware/cores/

```arduino
##############################################################

attiny84.name=ATtiny84

attiny84.upload.protocol=stk500
attiny84.upload.maximum_size=8192

attiny84.bootloader.low_fuses=0xe2
attiny84.bootloader.high_fuses=0xdd
attiny84.bootloader.extended_fuses=0xff
attiny84.bootloader.path=attiny84

attiny84.build.mcu=attiny84
attiny84.build.f_cpu=8000000L
attiny84.build.core=attiny84

```

Add this at the end in programmers.txt in hardware.

The pins: (dip14)

```arduino
                     +-\/-+
               VCC  1|    |14  GND
          (D0) PB0  2|    |13  AREF 
          (D1) PB1  3|    |12  PA1 (D9) 
             RESET  4|    |11  PA2 (D8) 
INT0  PWM (D2) PB2  5|    |10  PA3 (D7) 
      PWM (D3) PA7  6|    |9   PA4 (D6) 
      PWM (D4) PA6  7|    |8   PA5 (D5) PWM
                     +----+

```

The PA ports are also analog inputs. so PA0 = 0 and PA7 = 7  
The INT0 is the Interrupt port.(there is only 1)
